I like the quote "Out is important. While Levitt says he has never treated someone who held a fart in too long, there are dangerous side effects (including dizziness and headaches). Your colon becomes bloated, and theoretically, the methane and other lethal gases could add enough toxins to your blood to poison you. Levitt does not recommend holding in farts."
...now thinking of changing my nickname to Dr Fart Speaks! sorry Lisa. Mark (",)
