Uncle Peter made this incredible statement:

"This is a fact. -20C air does not make you cold, .
You might shiver if you were naked, but the
shivering will stop you getting any colder".

To me, it sounds like he's talking absolute bull****
and he should be sent to the funny farm, but is
there an element of truth in what he said?....

Nope. Its certainly possible to be quite active when
naked in -20C air and do fine, but just standing there
naked and shivering wont let you survive for long.

Active or not it doesn't matter. Shivering replaces active, it's
the same thing, your muscles are moving. You also have reduced
blood flow to the surface (all of you, not just your fingers and
toes and other sticky out things), and brown fat cells which
generate heat directly from calories.

Yup, which leads to frostbite on your extremities.

Your body won't allow that if you have a reasonably fit body.

your body doesn;t get the choice.

Your body is actually very resilient and can adjust blood flow to make
heat go anywhere it wants.

Must be why so many get frostbite on Everest, in the Arctic and
Antarctic etc.

Wimps.

You never could bull**** your way out of a wet paper bag.

I wouldn't freeze to death in one either.

Bull****.

I've gone hillwalking barefoot in the snow. My feet go cold and
numb
at first, then eventually they go red and warm up again.

and then your brain freezes and you post to usenet ;-)

I've never had a problem with my brain not working when I'm cold.

We can all see that it has never worked.

You're as infamous as me in here.

You never could bull**** your way out of a wet paper bag.

You think people don't believe you're a troll?

Fools abound.

It's been mentioned a couple of times in the last few days.

About you.
