This is certainly interesting.  You can send a company a fecal sample (you can also to oral or skin samples for those of you that are scatologically squeamish) and they will tell you what your gut flora is composed of and how it compares to everyone else who participates.  Not only that, but you will help them understand how dietary and lifestyle choices affect gut flora.  That is pretty cool.

If anyone that knows me is interested in participating, let me know.  The more you order, the less it costs.  I’ll order the kits and you can pay me.  Then we can brag about who has the best shit.  It’ll be fun.  And remember, it’s for science!
