Don't know if this has happened to anyone, but I use to be a pretty hairy guy on the legs, arms and chest.
I don't know when it happened, but sometime between the ages of 40 and 60, lost most of the hair on arms and legs, and although I still have hair on the chest, I was looking at a pic from a while ago my wife took of me laying in bed with the cat, and I couldn't get over how black my chest looked with all the hair, nothing like today.
I've also noticed with injuries that the skin is bruised or punctured, it takes like weeks or months if at all for the skin to look "normal" in the area in question.
For example, this is supposed to spell "HOT", and it stayed on me for like a week!

And they weren't lying, it was HOT! Don't ask...
