asian flush
Have you ever noticed that many asian people turn red when they start drinking? It's a genetic condition caused by an "atypical" (read: mutant) aldehyde dehydrogenase, which causes a buildup of acetaldehyde in the body. Acetaldehyde, being somewhat toxic causes the flushing and other nasty side effects, including wicked hangovers. Being the lucky fellow that I am, I'm the only one amongst my half asian friends who got this special gene, so in high schoolcollege, people would see me red eyed and pink and usually assume that I was enebriated when I was just getting started (just kidding, mom!). Actually, getting red and splotchy after drinking a beer or two is enough to put you off the whole drinking thing entirely. So it was with much interest that I saw a blog entry about how the asian flush might be an evolutionary adaptation to prevent alchoholism. However, anyone who has been to Japan can attest to the fact that asian flush isn't much of a discouragement to most of the male populace there!
