FYI: Doctors did a fecal transplant with a fat donor and a slim recipient. Then the recipient became fat.
Gut biome is also associated with good looks.
When you meet a naturally fit, good-looking person, ask for some of their poop.
Try to get the Tom Brady poop. (Was an actual South Park episode)
Can I get paid to donate at the poop bank? A good hearty Mexican meal could make me rich.
