32 centigrade is big heat as far as I'm concerned.
In the UK we have a bizzare mix of metric and imperial. As far as the use of stone goes, people use that these days only for bodyweight (presumeably because you weight less stone than pounds, making you lighter?). Almost everything else these days is in Kilograms. Beer and milk come in pints (and our pint is bigger than your pint) and fractions of pints, everything else comes in litres and millilitres. As for the weather? For joe public over say 35 or 40 years old, cold temps are in centigrade/celcius. Right now its between minus 1 and +1 degrees C but summer temps are in fahrenheit. On the TV and in the papers its always in Centigrade, being younger, I actually have no idea whatever how hot or cold a fahrenheit is and the conversion is not one that's easy to do in your head, if you can remember it.
It'd be simpler if I didn't even bother with the stone count when I post here, but I like to be redundant.
Larry: 2lbs a week is what I aim for. But I don't have your lung problems. I'm sure your doctor will keep you right.
