collecting

Hey everyone so I pick the bottom of my heels habitually. sometimes they are so raw from my picking that it is hard to walk for a few days. I have read that many people do the same thing, but I was wondering if anyone out there collects their skin pickings? I have a jar with a whole bunch of skin pieces I have collected over the past few months and it's strangely satisfying. anyway anyone else out there have a big collection of their skin pickings from feet or elsewhere? (I love the feet pickings because they are often so big and thick.
