Yes, as I have gotten older, my body hair has greatly changed. My legs have almost no hair on them anymore. I have been trimming my pubic hair for many years now. Sometimes I keep it trimmed really short or, like now, I keep it shaved smooth. During prostate cancer treatment with radiation and hormone therapy, I feel my hair got much thinner.
i'm a smoothie been that way for years now and now in my 60's i'm always curious if i was to let it grow out how much would it and how gray i would be but it has slowed growing over the years so it would take a while i'm sure and when it gets stubby i pull out the bodygroomer clip back to what i like best. the guys i'm with and 1/2 i see at camp are bushy and the ones my age have the gray pubes some thick but most sparse.
I wouldn't object to mine thinning; easier maintenance! Ha! Like others, I do notice that it is grayer than it once was. And, it always seems the way - you have hair where you don't want it and no hair where you do want it. But, hey life is great - GO NAKED!
What can you do. Youre correct, on old people hair tends to grow where you dont want it. I could live without the ear hair, uni-brow, and worst of all nose hair. I guess at least nose hair serves a purpose. With men especially, Im not sure what the purpose of pubic hair is anyway. Ive taken the week whacker to my pubic hair and it come back with a-vengeance.
