My boyfriend has been looking things up on the internet
to try and find out why my extremeties are always cold.

But it's not really that thoughtful because he's only doing it as an excuse to try and make me give up caffeine for my health because I'm trying to get him to stop smoking so much pot for his.

So ultimately he just wants me to suffer as much as him from withdrawals.

I believe it's just down to your metabolism and the nature of your blood flow
Some people's bodies naturally have a greater blood flow (ergo more warmth) to their extremities than others. The amount of warmth you generate on the whole depends on your diet and your metabolism (which, in turn, are partially linked). So it's not really your fault if you have cold hands.

Yeah that's what I said
when I go and give blood I have to clench and unclench my fist for the duration to make my blood flow into the bag and my hands go all tingly if I raise my arm for more than a few seconds so I think I just have lazy blood.

If I remember correctly...
Wasn't there a TV documentary that explained that women have cold feet and hands because their homeostatic system is set up to keep warmth at the core of their body to keep the ovaries toasty, wheras men are designed to shed a lot of heat to prevent their testicles from overheating, or somesuch - it's definitely to do with a biological need for women to keep internal organs warmer and thus they reduce blood flow to extremities to save body heat....

So you should be ok on the espresso

I think I read that too
that women have a higher core body temperature. My ovaries do feel quite toasty.

Yes, they do rather
Mmmm...

to get blood to your extremities, wave your arms back and forth like a spacker running.
That's what Bear Grylls does.

Bear Grylls warms his hands in the hotel he's staying in.

That's a harsh judgement.
If I'd spent the day filming in sub-zero temperatures, jumping naked into hazardous whitewater, eating scorpions and drinking my own piss out of a snakeskin, I reckon I'd probably demand a hotel room once 'cut' is called.

Ray Mears wouldn't do that.
Ray Mears would build his own hotel out of mud and fish that he'd caught using reeds. He's proper hardcore. He knows what to do. Always trust the survivalist who looks like he's eaten all the pies.

Exactly
I think if you're going to advertise yourself as a survivalist you shouldn't get to switch it off when you want.

There should be a Mears v Grylls survival-off or something. See who dies first. Although I've noticed that I've never actually seen Ray Mears making fire, he just shows the village kids how it should be done and then sets them to work on it.

I've seen Mears show New Zealand Maoris how their ancestors 'probably' made fire.
They seemed pleased - Grylls carries a flint rod and bashes his knife against it to make sparks. There is one essential difference between the two boys. Grylls just wants to leave wherever he is whereas Mears just wants to make it nice - it's like a wilderness makeover show. To be fair, he'd be better off up against Laurence Llewellyn-Bowen.

Bear Grylls
(bamboozled Can hear you getting fatter, Tue 2 Mar 2010, 13:33, Reply)

so that's what his fucking name is
I've been watching his show here in Spain for the past couple of months without knowing the name of him or the program.

they just showed the desert one where he eats rattlesnake

I know the behind-the-scenes survival advisor for that show
The crew first asked him whether you could make a water carrier from snakeskin, then a little while later whether you could drink your own piss.
He told Bear to drink a feck load of water before filming that one.

I'd seen another program
a few years ago about drinking piss in the desert.

it wasn't direct urine-to-bottle though- it involved covering and evaporating the water in the urine, and drinking that somehow
(bamboozled Can hear you getting fatter, Tue 2 Mar 2010, 14:27, Reply)

Yep, it's just distilling the water.
Easy if you have the materials to hand.

I might hasten to add that distilled water is just as bad because it strips the minerals and salts from your body.
