I was watching the 100% Qi weekend on UKTVG2 last night and there was a question about St Bernard dogs that was not fully explained. Why would giving Brandy to a person with hypothermia kill them?

Alcohol promotes heat loss by causing peripheral vasodilation, ie it causes the small blood vessels in your skin to expand and thus to radiate more heat*. You will have noticed how when you're 'trying' to loose heat your skin goes red (high blood flow), when you're 'trying' to conserve it your skin goes white (low blood flow).

NB vasodilation NOT vasodilatation here.

I see. Thank you very much. I'm no longer confused. :-)

My brain would explode!

(Then Natalie would eat the remains, as this is how she gets her intelligence).

Four episodes from the B series each day each shown twice from 9 pm, bit of a 'swiz' (its a VERY long time since I used that word) but worth watching of course.

We're lucky really, because 100%=1, and one episode's nothing to be bragging about.

If I was stuck in a snowdrift I think I'd probably want a drink.

Aww poor you. Come out from the wilderness and enjoy civilisation. Or at the very least, four episodes of Qi in a row. I feel nerdy, oh so nerdy.....
