[life] This scientist solved the mystery of belly button lint … ‘It was mostly people that had stomach hair who also typically found belly button lint. He proved it by shaving his own stomach, and seeing that he didn’t produce any belly button lint until his hair grew back. He also confirmed the seemingly obvious fact that lint originates from shirt fibers in two ways: by seeing that it always matched the color of the shirt he was wearing, and by chemically analyzing the lint and finding that it was mostly made of cellulose (the material that makes up cotton). It also contained some nitrogen and sulfur, likely from sweat and skin cells.’
