OpenBiome, a nonprofit medical resource clinic, puts your poo to good use.
It may sound strange, but human fecal matter can be used to aid those with an infection called Clostridium difficile. This infection often requires hospitalization and causes inflammation of the colon.
OpenBiome pays $40 per frozen sample of viable fecal matter, and sends it off to help those in need. Doctors then use said sample to help remove the infection, and treat their patients more effectively.
All samples are thoroughly tested prior to use and, according to The Washington Post, only about four percent are sent on for patient use.
Clostridium Difficile claims around 15 to as high as 30,000 lives annual, so, every donation counts.
