Foot Hair ... where did it go?

They say you never miss something until it's gone. I found that to be true of the hair on my feet/toes. I have always had a ton of hair on the tops of my feet & toes (to the point that I've endure regular Hobbit feet and Frodo jokes), but about four years ago it all suddenly went away!
I thought it might be related to circulation issues, but my doctor said the circulation in my feet was good; it's most likely part of my male-pattern baldness. Whatever it is, when I look down at my feet, even after four years of the hair being gone, it's like looking at someone else's feet on my body. LOL I miss seeing them as they were, nice and hairy.
Anyone else have hairy feet, or some other body part (besides the head), in which the hair just suddenly disappeared?
