      "prompt": "Plan the SHAPE of a holiday from these constraints, all real: family of five — two parents, kids 9 and 6, and gran who cannot walk more than ten minutes; £1,600 all-in for a week in August; flying from Manchester only; dad burns easily and hates 'just sitting on a beach'; the 9-year-old is obsessed with castles. Offer 2 distinct holiday shapes (types of place and trip, not named resorts), what each one trades away, and the single constraint you would challenge first because it costs the most.",
      "output": "# The pinch point first\n\nFive airline seats out of Manchester in August school holidays typically run **£150–£300 per person** — so £750–£1,500 of your £1,600 is potentially gone before anyone sleeps anywhere. Every shape below is built around surviving that, and it's why the challenge at the end is what it is.\n\n---\n\n## Shape 1: The \"one walled town\" holiday\n\n**What it is:** Fly short-haul (2–3 hrs, budget carrier, hold luggage minimised) to a small, compact historic town — the kind built inside or around a castle or medieval walls — and *don't move*. One self-catering apartment inside the old town for the whole week.\n\n**Why it fits the constraints:**\n- Gran: everything — bakery, square, castle gate, restaurants — is within a 10-minute shuffle. No transfers, no coaches.\n- The 9-year-old: lives *inside* the castle obsession for a week. Ramparts, dungeons, the lot, revisitable daily.\n- Dad: narrow shaded streets, stone, museums, markets — zero beach-sitting. Southern-Europe sun is managed by the siesta rhythm (out early, indoors 1–4pm).\n- Budget: one apartment (~£500–700), self-catering breakfasts and lunches, castle entry is cheap or free.\n\n**What it trades away:**\n- **Variety.** No day trips, no pool, no second location. By day five the 6-year-old has done the same square four times. You're betting the family is happy going *deep* rather than *wide*.\n- **Heat risk.** August in castle country abroad can hit 35°C — hard on gran and on burning dad. You mitigate it; you can't remove it.\n- **Financial slack.** This works at £1,600 but with almost nothing in reserve. One flight-price spike and it doesn't.\n\n---\n\n## Shape 2: The \"cool-climate castle circuit\" holiday\n\n**What it is:** Fly a short hop north or west rather than south — somewhere mild, green, and dense with castles — and base in a rural cottage or farm stay **with a small hire car**. Gran experiences everything as short bursts from a car park; the days are drive-20-minutes-see-a-castle-picnic-drive-home.\n\n**Why it fits the constraints:**\n- Gran: the car does the walking. Most heritage sites have close parking; ten minutes gets her to the keep and back.\n- Dad: 19°C and cloud cover is his ideal climate. Active days, no sunbathing culture at all.\n- The 9-year-old: a *different* castle every day beats one castle for a week.\n- The 6-year-old: farms, boats, castles-as-playgrounds — this shape suits the younger child better than Shape 1 does.\n\n**What it trades away:**\n- **Weather certainty.** It might rain four days out of seven. You're trading guaranteed sun for guaranteed comfort, and packing waterproofs in August.\n- **Money on wheels.** Car hire + fuel + a car seat is £250–£350 that Shape 1 spends on eating out. This shape means self-catering almost every meal.\n- **\"It doesn't feel abroad.\"** Cool, green, drizzly-possible — some of the family may feel they didn't get a \"summer holiday.\"\n\n---\n\n## The constraint I'd challenge first: **\"flying from Manchester only\"**\n\nNot the budget, not August — the flying. Here's the arithmetic:\n\n- Flights are the single item consuming **up to 90% of the budget**, and they buy you nothing except position.\n- August is nearly immovable (school-age kids), and the budget is presumably real. But \"flying\" is often a *preference dressed as a constraint* — what the family actually wants is \"somewhere that feels like a proper holiday,\" not an aircraft.\n- Swap flying for **driving or the ferry/rail from the Manchester area**, and £1,600 stops being survival money and becomes *abundance*: castle-dense regions of Britain and Ireland are reachable in 2–4 hours, a week's cottage is £600–£900, and you'd have £600+ left for eating out, boat trips, and castle tickets — luxuries neither flying shape can afford.\n- It's also quietly the **best shape for gran**: no airport standing, no gate-to-plane walks (which alone can breach her ten minutes), her own seat and stops on demand.\n\nSo before booking either shape above, I'd put one question to the family: *\"If I could double the quality of everything else, would you give up the plane?\"* If the answer is no — flying is genuinely the point — then Shape 1 for a family that wants heat and atmosphere, Shape 2 for one that wants activity and ease.",

Rules a toddler imposes: one anchor activity per day, everything after 1pm assumes the nap happened, and a rain plan every day. Say which attraction you would DROP entirely and why.",
      "output": "# Edinburgh with a Toddler: 3 Days, 5 Attractions\n\n## The Drop: Camera Obscura ❌\n**Why:** Cramped stairs are the single worst feature for a toddler-and-buggy setup — you'd be carrying a child AND folding a pushchair through tight Victorian staircases, in crowds. It's also right next to the Castle, so you lose nothing geographically. Its one advantage (open until 8pm) is useless when your day effectively ends at toddler bedtime anyway.\n\n---\n\n## Day 1 — Anchor: Edinburgh Castle 🏰\n- **9:30 sharp:** Arrive at opening. Toddler energy is highest, crowds are lowest. **Use a carrier, not the buggy** — the steep cobbled approach is buggy hostile.\n- **~11:30:** Done. Lunch nearby, then home/hotel for the nap.\n- **After 1pm (nap achieved):** National Museum of Scotland — it's a 10-minute walk from the Royal Mile, free, and warm. Low-stakes: leave whenever the toddler melts down, because it cost nothing.\n- **☔ Rain plan:** Flip the day. Museum in the morning, Castle attempt post-nap if it clears; if it doesn't, the Castle moves to Day 3 and Botanics gets bumped (see below).\n\n## Day 2 — Anchor: Dynamic Earth 🌋\n- **10:00 open:** The one fully **buggy-friendly** anchor, so this is your \"easy logistics\" day. Interactive and toddler-tolerant.\n- **~12:30:** Lunch, nap.\n- **After 1pm:** Portobello Beach — open access means zero time pressure. Sand digging is peak toddler content, and a late-afternoon arrival is fine.\n- **☔ Rain plan:** Dynamic Earth is already indoors, so the morning survives. Afternoon: return to the National Museum (free = infinitely repeatable rain shelter). Portobello slides to Day 3.\n\n## Day 3 — Anchor: Royal Botanic Garden 🌿\n- **10:00:** Free entry, wide paths, toddler can run loose safely — a deliberate low-structure final day. Buggy-friendly.\n- **12:30:** Lunch, nap.\n- **After 1pm:** Whatever got rained out earlier in the trip (Portobello or Castle), OR just return to the Botanics until 6pm — the late closing gives flexibility.\n- **☔ Rain plan:** The Botanics' **glasshouses** are the built-in escape hatch; if it's a total washout, the Museum absorbs the day again — being free, it never punishes a 45-minute toddler-length visit.\n\n---\n\n## Design logic\n- **Anchors go in the morning** — never gamble a paid ticket on post-nap mood.\n- **Free attractions (Museum, Botanics, beach) fill afternoons** — if the nap fails and you bail after 30 minutes, you've lost nothing.\n- **The Museum is the trip's rain sponge** — free and central, it backstops all three days.",

      "output": "# Kraków, February, 4 Days — Cabin Bag Only (Cold-Sensitive Edition)\n\nKraków in February typically sits between **-6°C and +2°C**, with wind chill making it feel colder, especially around the exposed Main Square and along the Vistula. The strategy: **thin, trapping layers you can add/remove, not one heroic thick item.**\n\n---\n\n## 👕 WORN ON THE PLANE (your bulkiest items travel on your body)\n\n- **Merino wool base layer top** (long-sleeve)\n- **Merino or thermal leggings** under trousers\n- **Fleece-lined or wool-blend trousers** (softshell hiking trousers work brilliantly and look fine in a city)\n- **Midweight fleece or wool jumper**\n- **Your big insulated coat** — knee-length, hooded, ideally down or synthetic fill. Wear it, don't pack it; it doubles as a blanket on the plane\n- **Waterproof insulated boots** with grippy soles (pavements get icy; cobblestones + slush is Kraków's winter specialty)\n- **Merino socks** (midweight)\n- **Scarf, warm hat, and gloves** stuffed in coat pockets\n\n---\n\n## 🎒 PACKED IN THE CABIN BAG\n\n**Base layers (rotate):**\n- 2 × merino base layer tops\n- 1 × spare thermal leggings\n- 4 × merino or thermal socks (cold feet = miserable day; this is where you don't skimp)\n- Underwear × 4\n\n**Mid layers:**\n- 1 × thin packable down/synthetic gilet — *this is your secret weapon*: worn under the coat on the coldest days, worn alone indoors in a chilly Airbnb\n- 1 × lightweight second fleece or thin wool jumper (alternate with the worn one)\n\n**Extremities backup (cold-sensitive essentials):**\n- 1 × thin liner gloves (worn under main gloves, or alone for phone/photos)\n- 1 × buff/neck gaiter (seals the gap a scarf leaves; doubles as extra hat layer)\n- Handful of **disposable hand warmers** — weightless, and transformative during an evening walk through the Christmas-market-hangover chill of the Old Town\n\n**Other:**\n- 1 × smarter thin top for dinner (a fine merino roll-neck does dinner *and* functions as a layer — pick items with two jobs)\n- Sleepwear (warm — Polish apartments are usually well-heated, but hedge)\n- Lip balm + rich moisturiser (the dry cold will chap you fast)\n- Toiletries under 100ml, chargers, adapter (Poland uses type C/E)\n- Packable tote for day use\n\n---\n\n## ❌ THE DELIBERATE OMISSION: **Jeans**\n\nThe single most reflexively packed city-break item, and the worst possible choice for Kraków in February. Cotton denim has almost no insulation, actively conducts heat away from your legs when cold, takes a full day to dry if it gets wet in slush or snow, and is one of the heaviest, bulkiest things you can put in a cabin bag. For someone who feels the cold, jeans are a liability, not a neutral. The thermal-leggings-plus-lined-trousers combination is warmer than jeans by an enormous margin, dries overnight, and weighs half as much.\n\n**The layering payoff:** on a mild day you drop the gilet and liner gloves; on a -10°C day you're wearing base + fleece + gilet + coat and you're genuinely comfortable — with nothing in your bag that only works in one scenario.",

If you can't ditch the bags, the next-best mitigation is booking a **Flexible/Fully Flexible NatEx fare** (or checking the next departure time) so a missed 16:00 is an inconvenience, not a lost ticket.",

If it's cancelled, the £140 is likely lost.\n- Verdict: £0 extra, but you're gambling £140 and a day on the storm passing.\n\n**(b) Eurotunnel 10am — £95 for certainty**\n- The tunnel is effectively weather-proof; this is the only option that removes the storm from the equation.\n- 35 minutes, dog stays in the car with you — by far the best option for the spaniel.\n- **Bruges night:** arrive Calais ~11:35 local, Bruges by ~13:30. You save the full £140 night *and* get an afternoon and evening in Bruges. The £95 buys back £140 of hotel plus half a day of holiday. Net, it's the cheapest real outcome.\n\n**(c) Harwich–Hook tonight — the worst of everything**\n- 3 hours' extra driving starting at 9pm+, a compulsory cabin (probably £50–150 with a pet-friendly one), extra fuel, and a much longer crossing on the same weather system, just further north.\n- **Bruges night:** you arrive Hook late afternoon, Bruges around 19:00–20:00 — you \"use\" the room but only to collapse in it, exhausted, having paid *more* than option (b) for the privilege.\n- Verdict: highest cost, highest fatigue, hardest on the dog, and it barely saves the night it's supposed to save.\n\n**So: (b).** It's the only option where the outcome is certain, and certainty is exactly what a £140 non-refundable booking needs.\n\n### Right now tonight, in order\n\n1. **Book the 10am Eurotunnel slot immediately.** Everyone else off the cancelled ferry is rebooking right now — availability is the whole plan. Add the dog to the booking (~£22 pet fee, check it's included in the £95 figure).\n2. **Only after the tunnel is confirmed**, deal with the ferry booking: request the weather-cancellation refund, or a free transfer to the 2pm sailing if that costs nothing — a free backup is worth holding.\n3. **Check the dog's paperwork:** microchip details, animal health certificate/pet passport, and note that Eurotunnel requires check-in at Pet Reception — plan to arrive Folkestone ~90 minutes early.\n4. **Message the Bruges hotel:** confirm the booking stands, confirm the dog is expected, and give a new arrival time of early-to-mid afternoon.\n5. **Fuel the car and pack it tonight** — passports, dog food, water bowl, lead, poo bags, blanket.\n6. **Set the alarm** working back from a ~08:30 Folkestone arrival, and go to bed — no 3-hour drive to Harwich, which is half the point.\n7. **Morning contingency in your pocket:** if anything goes wrong at the tunnel, the (free-transferred) 2pm ferry is your fallback.",

For each item, state what specifically must be checked before booking — the exact question to ask, not 'check accessibility' — then reorder the day so the item most at risk of disappointing comes first while energy is highest, naming which one that is.",
      "output": "## What to check, item by item\n\n**York Minster**\n- \"Is the step-free entrance (the west/south door with the ramp) open at the time we're visiting, or do accessible visitors need to be let in by staff?\" — the accessible door is sometimes staffed rather than simply open.\n- \"Does the lift down to the Undercroft museum take a self-propelled chair — what are the door width and cab depth — and does it need a staff member with a key?\"\n- Accept now that the central tower (275 spiral steps) is out; ask whether there's a virtual tower experience so it isn't a surprise on the day.\n- \"Where is the accessible toilet, and is it inside the ticket line or back outside?\"\n\n**City walls**\n- The honest question is: \"Is there *any* access point to the wall walk with two steps or fewer?\" The answer will almost certainly be no — the bars (Bootham, Monk, Micklegate) are reached by full flights of 15–20+ stone steps, and the parapet walk itself is narrow with drops.\n- So the real check is: \"Where are the best street-level viewpoints of the walls and bars?\" (e.g., Bootham Bar from Exhibition Square, the walls from Lord Mayor's Walk). Reframe this item now, before the day, as *seeing* the walls rather than walking them.\n\n**Riverboat cruise (City Cruises, King's Staith / Lendal Bridge)**\n- \"Given the river level forecast for that day, what will the gangway gradient be at your landing stage, and will crew assist a self-propelled chair up it?\" The Ouse rises and falls dramatically; the ramp angle is decided by the river, not the company.\n- \"Which landing stage is step-free — King's Staith or Lendal — and which sailings use it?\"\n- \"Once aboard, is the main deck step-free, can the chair stay on that deck for the whole cruise, and is there an accessible toilet on board?\"\n- \"If boarding is refused on the day because of river height, do you rebook or refund?\"\n\n**Afternoon tea (e.g., Bettys)**\n- \"Can you guarantee a ground-floor table with space to sit *in* the wheelchair at the table?\" — some rooms (Bettys' Belmont Room) are downstairs by staircase only.\n- \"Is there a threshold step at the entrance, and is the accessible toilet on the same floor as the table?\" Historic tea rooms often have toilets in the basement.\n\n**The Shambles**\n- Nothing to book, but for any specific shop: \"Is there a step at your door and how wide is the doorway?\" — most Shambles shops have a step and doors under 70cm.\n- Check the street itself: setted/cambered surface, and it becomes near-impassable in a chair at midday crowds. Timing is the accessibility measure here.\n\n## The reordered day — riverboat first\n\n**The riverboat is the item most at risk of disappointing.** The walls are *not* the answer, counterintuitively — they fail the check outright, so they get replanned in advance and carry no day-of risk. The cruise is the one item where a \"yes\" on the phone can turn into a \"no\" at the gangway, because the ramp gradient depends on that morning's river level, and boarding is also the single hardest physical push of the day. Do it first, on the first sailing, while arm strength is highest — and if boarding fails, there's still time to rebook an afternoon sailing.\n\n1. **Riverboat — first sailing (~10:00–10:30).** Fresh arms for the gangway; maximum fallback time.\n2. **Minster (late morning).** Short, flat push from the landing stage via Lendal; the lift and level entrance make this low-effort.\n3. **The Shambles (early afternoon).** The cobbles are genuinely tiring to self-propel — do them before the rest stop, not after, and before peak crowds if possible.\n4. **Afternoon tea (mid-afternoon, e.g., St Helen's Square).** Deliberately placed as the recovery block after the two hardest surfaces of the day.\n5. **Walls at street level (late afternoon).** The reframed version — Bootham Bar and Exhibition Square are minutes from Bettys, it's smooth pavement, and it's a gentle, low-stakes end to the day.",

Explain plainly: what 'pre-existing condition' means to an insurer, what non-declaration does to a claim — including a claim unrelated to the condition, why 'but I feel fine' is irrelevant to underwriting, and the two questions to ask when comparing policies. No naming insurers, no scare tactics.",
      "output": "# Travel insurance and your medical history: the plain version\n\n## What \"pre-existing condition\" means to an insurer\n\nTo an insurer, a pre-existing condition is broadly **anything you've been diagnosed with, treated for, prescribed medication for, or investigated for** — usually within a set look-back period, and often at any time for heart conditions and diabetes.\n\nSo for you, that means:\n\n- **The stented artery** — yes, even though it was fitted in 2019 and the procedure went well. A stent is treatment for a heart condition; the condition doesn't stop being \"pre-existing\" because it's been managed.\n- **The type 2 diabetes** — yes, even if it's diet-controlled or you consider it mild.\n- **Related items** you might not think of: blood pressure or cholesterol medication, any check-ups or referrals you're waiting on, and anything a doctor has told you they want to monitor.\n\nThe rule of thumb: if a doctor knows about it, the insurer wants to know about it.\n\n## What non-declaration does to a claim\n\nIf you don't declare a condition and later claim, the insurer checks your medical records as part of assessing the claim. If they find something undeclared, they can:\n\n- **Refuse the claim** connected to that condition.\n- **In some cases, treat the policy as if it never existed** — meaning even claims *unrelated* to the condition can be affected.\n\nThat second point is the one people miss. If you slip by the pool and break a wrist — nothing to do with your heart or your diabetes — the insurer can still investigate your health history. If the policy is voided for non-disclosure, the wrist claim can fail too, because there's effectively no valid policy behind it.\n\nMedical treatment abroad, even in Spain and its islands, can run into large sums, and repatriation costs more still. Declaring properly is what keeps the policy solid underneath *every* claim, not just the medical ones.\n\n## Why \"but I feel fine\" doesn't matter\n\nUnderwriting isn't a judgement on how well you are today. It's a **statistical assessment of risk** — the insurer is pricing the likelihood of a claim based on medical facts, not on how you feel.\n\nTwo things follow from that:\n\n1. **Feeling fine isn't a medical status.** A stented artery that's giving you no trouble is still a stented artery on your records, and it's the records the insurer will check at claim time.\n2. **You don't get to decide what's relevant — the insurer does.** The question isn't \"do I think this matters?\" but \"did they ask about it?\" If the medical screening asks, answer it fully and let their system do the pricing.\n\nDeclaring your conditions will likely add something to the premium. That extra cost is exactly what buys you cover for the things most likely to need it.\n\n## The two questions to ask when comparing policies\n\n1. **\"If I declare my stent and my diabetes, are they fully covered — or excluded, or covered with a higher excess?\"**\n   Some policies cover declared conditions completely; others accept your declaration but exclude claims arising from those conditions. A cheap policy that excludes your heart is not comparable to a dearer one that covers it. Get the answer in writing.\n\n2. **\"What do I have to tell you if my health changes between buying the policy and travelling?\"**\n   If you get a new diagnosis, a medication change, or a referral before departure, most policies require you to inform them. Know what triggers that duty and what happens to your cover (and your money) if the answer changes things.\n\nOne practical extra: when doing the medical screening, have your **repeat prescription list and diagnosis dates to hand**, and answer every question literally and completely. It takes ten minutes and it's what makes the certificate worth the paper it's printed on.",

Build the realistic jet-lag plan: how to handle sleep on the plane, the first-day rules on daylight, caffeine cut-off and the short-nap clause, and what the body will genuinely feel like at that Friday 7am despite all of it — no pretending it can be fully solved.",
      "output": "# The honest math first\n\nTokyo is 8 hours ahead of Manchester (9 in winter). Your Friday 7am meeting is **10–11pm Thursday on your body clock**. You cannot fix that in 46 hours — eastward adaptation runs at roughly one time zone per day, so full adjustment would take over a week. This plan isn't about solving jet lag. It's about arriving at that meeting *functional* instead of wrecked, and knowing exactly when the wall will hit.\n\n---\n\n## On the plane (Wednesday departure)\n\n- **Set your watch to Tokyo the moment you board.** Stop calculating UK time. This is psychological, but it matters.\n- **Eat the first meal service, then commit to sleep** during the middle block of the flight — this roughly overlaps Tokyo's Wednesday night. Eye mask, earplugs/headphones, seatbelt visible over the blanket so crew don't wake you.\n- **Melatonin (0.5–3mg) at the start of your sleep attempt** if you use it. Skip alcohol entirely — it fragments exactly the sleep you're trying to bank.\n- **Realistic expectation: 3–5 broken hours, not 8.** That's fine. That's the budget.\n- **Last 2–3 hours of the flight: stay awake.** Cabin lights, breakfast, water, walk the aisle. You're rehearsing Thursday morning.\n\n---\n\n## Thursday — arrival day rules\n\nThis is where most advice gets it wrong. \"Get daylight immediately\" is the standard line, but after a ~9-hour eastward jump, your body's temperature minimum (around 4am UK) lands at roughly **1pm Tokyo time**. Bright light *before* that point pushes your clock the wrong direction.\n\n**Morning (9am–1pm):**\n- Sunglasses outdoors. Not full darkness — just don't flood yourself with bright light.\n- One coffee on landing is allowed. Keep moving: hotel check-in, walk, errands. No lying down.\n\n**Afternoon (1pm–6pm):**\n- Now flip it: **get outside, walk in daylight.** This is the window where light actually drags your clock toward Tokyo.\n- **Caffeine cutoff: ~1–2pm.** One coffee with lunch, then done. Anything later is stealing from Thursday night, and Thursday night is the whole game.\n\n**The short-nap clause:**\n- If you're genuinely failing — eyes closing mid-sentence — one nap is permitted. **20–30 minutes max, alarm set, completed before 3pm, ideally in a chair, not under the covers.** A nap that runs to 90 minutes on arrival day detonates the plan.\n\n**Evening:**\n- Light dinner, early. Dim the hotel room from ~8pm, screens down or off.\n- Melatonin around 9pm if using. **Bed 9:30–10pm.** Your body thinks it's early afternoon; you'll be tired from the travel anyway. Take what sleep comes.\n\n---\n\n## Thursday night — the 3am ambush\n\nYou will very likely wake between 2 and 4am, wide-eyed, because your body believes it's Thursday evening in Manchester and the day is just getting going. This is normal and expected. The rules:\n\n- **Do not turn on lights. Do not pick up the phone.** Blue light plus stimulation at 3am and you're finished until dawn.\n- Stay in the dark and accept dozing as the goal, not deep sleep. Fragmented rest still counts.\n- Alarm set for 5:30–6am regardless of how the night went.\n\n---\n\n## Friday morning\n\n- Up at 5:30–6am. Shower hot-then-cool, get **bright light immediately** — curtains open, or better, a short walk outside on the way to the meeting.\n- Real breakfast, even if you're not hungry (your gut clock is even further behind than your brain).\n- **Coffee timed 30–45 minutes before the 7am start** so it peaks in the room, not in the taxi.\n\n---\n\n## What 7am Friday will actually feel like\n\nNo pretending: your body will be at ~10pm on maybe 4–6 hours of fragmented sleep across two nights.\n\n**The first 60–90 minutes will be genuinely okay.** Adrenaline, caffeine, and morning light are a real cocktail — you'll be alert, present, socially sharp. But know the specific deficits:\n\n- **Complex reasoning and mental arithmetic will lag.** Have every number written down. Don't improvise calculations live.\n- **Word-finding will occasionally stutter** — a half-second reach for a term you know cold. Slow your speaking pace deliberately; it reads as gravitas, not fatigue.\n- **Front-load everything important into the first hour.** Your best material goes first, not built up to.\n\n**The cliff comes 11am–2pm Friday.** That's 2–5am on your body clock — the circadian trough, the deepest biological demand for sleep you'll face all trip. If there's any chance the meeting runs long or moves to lunch negotiations, that's where you're weakest. Protect that window if you can: no signing, no final terms, nothing requiring judgment. If the schedule forces it, another short nap-and-coffee before noon is the emergency valve.\n\nThe plan gets you a strong 90 minutes at the right moment. That's what's actually on offer — and it's enough, if you build the day around it.",

In the UAE, undeclared codeine can mean arrest, prosecution, and imprisonment even for personal medical use. Do it legally instead: carry the medication in its original packaging with a doctor's letter and prescription, and check the UAE Ministry of Health's controlled-medicines approval process before you fly — some drugs require prior electronic permission.",
