So I didn’t think this was weird, but apparently it is. This morning I got out the shower, walked into the bedroom and went to put socks on. As I did so, my little toenail was loose. As in, the whole thing. So I just pulled it off. And there’s a whole new fresh one grown underneath. I’ve had no trauma on the nail, it just happens randomly and fairly regularly; about once every few months or so.
I became aware that DH was looking at me, horrified. He assured me that toenails dropping off to reveal fresh new ones underneath is absolutely not a normal thing, and recommended I sell my body to science 
What weird thing does your body do?
