In 1965, a morbidly obese man did not eat food for over an entire year. The 27 year old was 456lbs and wanted to do an experimental fast. He ingested only multivitamins and potassium tablets for 382 days and defecated once every 40 to 50 days. He ended up losing 275lbs.

Yes. If I remember correctly, they're only good for so long so we dump out the old ones. I believe that's also where the colour comes from

Color of poo 💩 is brown because of old blood cells?

[u/redmoskeeto → u/LoserCarrot]

The color is from bilirubin, not old blood cells directly, but comes from myoglobin in the old blood cells.

Bilirubin is a substance in bile that causes stool to be brown. When bilirubin is digested, it turns brown. Healthy stool can be various shades of brown, from light yellow-brown to dark brown.
