I think I eat quite healthy, I don't eat processed foods, no coffee, no alcohol. And I don't tend to eat a lot of meat or deep-fried food. No a lot of sugar, either. I am 42 and don't use anabolics.

What does my back have to do with anything though?

if you're 42, you're just getting older. moisturizing after a shower and avoiding excessive sun is all you can really do. use sunscreen/wear a hat.

you probably don't have to do this but if it makes you feel better, go to a dr. they might be able to see if youre having issues with collagen or something.
