Random: From my calendar to yours

Another nifty (and thoroughly wacko) "traveling advice":

Eat lots of bananas.

They've loads of potassium which will save you from leg cramps and tryptophan which induce drowsiness.

So, because turkey's also loaded in tryptophan, that theoretically means that eating turkey will make you sleepy. But that makes no sense because most of your tryptophan are digested by the E coli. in your gut and tryp. is an essential amino acid and the tryp. operon in the E coli. is an repressible operon, meaning that even if you don't eat tryp. the E coli. will still be making its own and you'd still have it in your body.
Maybe eating it just means you'll get a temporary spike in your body's level of tryptophan, and that makes you drowsy.

Anyway--so, watch out for bananas.
