My fingers don't mind the cold, they in fact go RED to increase blood
to
them to prevent frostbite.

How can that be!? Your blood reduces flow to your extremities when
very
cold, to protect your vital organs.

Your fingers and toes are more important. Your "vital organs" are
inside you and much warmer anyway. Try shoving just your hand in a tub
of cold water right now. Leave it in there for a while, your hand will
go red. That's MORE blood to protect it.

Tell me! what parts of the body tend to get frostbite first if it's not
fingers and toes?


Nothing does if you're fit and healthy.


Must be why the fit and healthy get frostbite climbing Everest.

Shutting off your extremities is ****ing stupid.


Beats dying.

You need those to walk on, therefore they are as important as your "vital
organs".


Even more pig ignorant than you usually manage.

You'll find they are more likely to get blood flow if you're using them
too.


Yes, most of those that do get frostbite of their extremitys
get that at night when they arent using them. Not always tho.
