I have a zillion, neck and "torso" :-) I've never bothered taking them off as they can grow back. I heard from one dermatologist that they're related to weight gain which I can believe. My mother had a lot of moles and I do too so I just ignore them all (except making sure none of them are cancerous or otherwise need removing). Some of the skin tags just "die" and come off themselves.
