I can't find any hard facts on the subject, but if every Drivers Ed course I've ever taken (and to get out of tickets I've taken allot), they say that most of the alchohol in your body is processed and released through sweat more than anything else.

And from personal experience, when I drink, no matter what the temperature is or my level of activity, I reek of whatever alchohol I've drank. My wife knows what I've drank by the smell of my skin.
Sorry for the only slightly disgusting explanation, but I'm Irish.

If you pr!ck us, do we not bleed? If you poison us, do we not die? And if you wrong us, shall we not revenge? If we are like you in the rest, we will resemble you in that the villany you teach me, I will execute, and it shall go hard but I will better the instruction. MOV
