I get my eyebrows shaped once in a while (probably about 3 times a year.) I shave my underarms once in a while, but not all the time, as the skin gets sore. Even more rarely, I wax my legs. I haven't done them for ages, but I am not particularly hairy anyway, and I don't reckon most people would notice without being right up close.
I do sometimes wonder how militant I might feel about depilation if I were hairier. I mean, it's quite easy not to shave if you don't have very noticeable hair in the first place. Mind you, I also don't dye my hair, and the white hairs are becoming more noticeable, particularly in one streak. So I suspect I would still not be very active when it comes to depilation.
