Drain Bamage

I once mused with a friend over the consequences of heavy drinking and the brain cells it kills, and wondered whether it really does make you stupider. This friend of mine speculated that "the herd is only as fast as its slowest members," so killing off the weak links through drinking might make you actually smarter. Comforting. Turns out we were both wrong, drinking may not kill brain cells at all! Thanks, Ann.
