I’m sure there’s some obvious answer to this, but for the life of me, I can’t figure it:
When I had surgery earlier this year, I had a number of staples which had to be removed about 10 days later. The skin was starting to redden from their presence, though they would have had to come out anyway. Much later, I started thinking about all the piercings people get. What keeps the tissue from getting really red and then totally rejecting these foreign objects?
