Codeine is wonderful stuff. Very morish though.

Whenever I heard a report of some actor or other being "addicted to painkillers", I could never understand how someone could become addicted to a couple of paracetamol.

Having been given codeine as a painkiller, after a couple of days I could already understand how people get addicted, and actually found myself looking at the time and thinking "Great, just another hour and I'll get my codeine again!". I'd imagine that if someone is given a larger dose, takes it for an extended period etc, then it would be very difficult to come off it as long as they have access to it.

If the weakest of the opioids can be that potent, I can understand how heroine addiction ruins so many lives.

But in answer to the original question, isn't it just a case of the chemical blocking neuroreceptors, in which case it will only "fit" onto the pain receptors? Not a medic, just finally getting to use what I learned in General Studies all those years ago

Most drugs absorb the kidneys first, as that is a way to absorb them into the bloodstream, aka alcohol, and an overdose of such drugs will break down the kidneys first, once the kidneys are broken down, and, Meningitis then steps up, as the Kidney breaks down..

I got the answer from someone who's actually been to medical school:

Ibuprofen is an anti-inflammatory drug. It's an improved version of paracetamol but it's sufficiently different that you can use both at the same time.

They work on the brain to fool it into thinking there is no pain.

bit like a politician

I guess this question was tongue in cheek?

But if not here is the answer . .

A flask doesn't 'keep' things hot or cold but simply slows down the rate of change.

Temperature allways equalizes due to conduction.

If you put hot food on a cold plate the plate will warm up causing the food to cool down. leave them long enough and they will both be exactly the same temperature which due to the same process with the surrounding air will be at the room temperature.

All a flask does is prevent the conduction of heat by creating a gap using a vaccum of air to prevent the conduction of heat.

Of course they aren't perfect as the lid allows the conduction of heat and the vacuum space is also small allowing radiated heat to cross the gap.

Good answer - I've often worked in garages, and standing on cold concrete makes your body go cold, but stand on a piece of cardboard, it's OK. Stick your brew on a piece of steel in the workshop, and it's cold in minutes. Stick it on a coaster, and it retains its warmth.

Standing on cardboard supping brews sounds like an ace job.

a thermos flask, ok i know it keeps stuff hot and it keeps stuff cold, but how does it know which is which?

David Beckham goes shopping, and sees something interesting in the Kitchen department of a large department store. “What’s that?” he asks.

“A Thermos flask,” replies the assistant. “What does it do?” asks Becks. The assistant tells him it keeps hot things hot and cold things cold.

Really impressed, Beckham buys one and takes it along to his next training session. “Here, boys, look at this,” Beckham says proudly.

“It’s a Thermos flask.” The lads are impressed. “What does it do?” they ask.

“It keeps hot things hot and cold things cold, “says David.

“And what have you got in it?” ask the lads.

“Tomato soup and a Choc ice,” replies David.
