excuse me? I don't fart. ever.

however, there are lots of ingredients in sports food that could cause flatulence (especially all those preservatives).

I've been reading a very interesting book that says that after 30 or so, we all start falling apart and farting because our bodies are so messed up and we've got parasites and our sphincter muscle isn't strong enough to hold em in. The book has nothing to do with any of that though -- it's about older women and tadpoles.

Okay, so my question was a bit rhetorical -- I already knew the answer but it always amazes me.

But, my friend Rick sent a bit more information about our ability to smell, well you know, our pee.

"The funny smell comes from metabolites from the breakdown of some of the chemicals in asparagus, mostly the amino acid asparginine, and those metabolites are quickly filtered out by the kidneys and make their way out as 'pee'. About 3/4 of the way down in the Wikipedia page on asparagus ( http://en.wikipedia.org/wiki/Asparagus) they discuss it. Interestingly, everyone excretes the stinky chemicals, but some folks cannot smell it. The ability to smell it is controlled by a single gene with simple inheritance, the lack of ability to smell is the recessive trait. Back when I taught Biology classes (large classes, 200+ students) it was an interesting experiment during the genetics section to feed everyone asparagus during class then poll during the next session to see who could and who could not smell the after-effect. I take it since you ask the question that you exhibit the dominant trait."

Probably just too many beans. And what's up with not farting, ever?!? Puh-leeze ;)

Older women & tadpoles? I want to read that one.

yeah, tadpoles. you know, the youthful version of prince charming (the frog)? I think the formula goes something like this. the ideal age for a man = half your age + 7 years.

not sure where I got the book. the audience is really older women (50+). some interesting thoughts though.
