Just curious but does anyone use nitrogen to fill tyres?
Been thinking about it but not sure if its worth it really as topping it up could be a pain
Pointless in a road car, air is 78% nitrogen anyway! :lol: :lol:

What about in exhaled air?
It'll be the same won't it? Humans don't use Nitrogen IIRC..... which hospital do you work at.... :lol:

Good work hippy! You wouldn't believe how many med students we catch out with this one.
Ah, a test! :lol:
It's just common sense isn't it? They should be kicked out for getting that wrong!
Most med students aren't smart (or at least have common snese), their parent's have just got lots of money to send them to public school/med school
Another one is, "If you swallow a peanut, which lung is it more likely to go down?"
