Nose hairs bleed? Ummm I never had that happen, I use to use cuticle scissors, which hurts and does bleed if you nick yourself. But the hair themselves, not mine anyway. BTW, now I shave right up in there as high as I can (again watch the nicks, I have a big nose, I guess) and use a (japanese) trimmer thing that my GF has for getting in there deeper. Plucking works too. Nice and clean! Works in the ears too, which I also shave the outer edges of.
One last thought, isn't it strange that we say we stop growing when we are 20 or so, when in fact, I seem to have more things growing (nose,ears, hair in new spots, tummy if it is not watched, I swear even my ____ is still getting bigger) since my 40s than I did when I was 20.
