lost your underarm hair?

I no longer have underarm hair after a series of illnesses.
Has anybody else lost their underarm hair? and for what reason?

Crap man don’t do that I thought you found mine…

I wax, which royally sucketh, but it lasts longer than shaving, which is also a pain in the ass. So I guess I didn’t lose it so much as I ripped it out, screaming all the while, but it’s gone just the same.
