Tumble will return with all new episodes for Season 7, starting September 17! In the meantime, enjoy one of our favorite episodes of Season 6. 

If someone asked you to collect your poop every day for a year, would you say yes? That’s what microbiologist Lawrence David did, after watching a movie about a man who said yes to everything. Accepting the challenge led to a year of very stinky international adventures, turning Lawrence into the James Bond of poo. And, he loved every minute of it. Join us for the incredible story of a secretive project about the human microbiome.
