I *think* what happens is that, when cold, your body tries to keep the warm blood in the core of your body. It does this by constricting the arteries and capillaries in your limbs, reducing blood flow through them. Alchohol counters this effect and causes the capillaries to expand again. So, warm blood flows from your core into your limbs and makes you feel warm. Unfortunately, this also means that the cold blood that was trapped in your limbs gets circulated to your core, which can drop your core temperature...a Bad Thing. So, the warmth is only an illusion.
Hopefully someone with more bio can elucidate further...

My opinion is yes, we need more ways to create plastic. Oil is too valuable as an energy source to waste it making Nintendo cartridges. It would be best to run off renewable sources, like solar or wind, but until they become (more) cost-effective, at least we'll be reducing the ammount of fossil fuels we use up.
hmmm...I'd be more inclined to say that oil is too valuable to waste as a fuel source.
