I swear, I think the funky skin elasticity and denting (and loss of mass too) is due to plain aging. I'm 30 now, and I notice a huge difference in my skin elasticity. I think collagen levels must have something to do with this. I also notice more 'muscle definition'...more in the form of muscle outlines versus actual muscle bulk. I'm in good shape...only 110 lbs, but I definitely don't strive for muscle definition when I exercise. I think our bodies just change like this as we age. Really I do. Also, if you're paying more attention--you'll notice a lot more than you ever did before.
Compare the hands of a woman in her twenties to a woman in her sixties....you'll notice a HUGE difference. The woman in her sixties will have far more denting (like the metacarpal bones actually stick out) and wrinkling.
Really, it's purely aging.
The circulation thing you said makes sense too. I don't think it's necessarity tied to nervous system function--just general changes in aging too.
Increased blood circulation makes things puffier--uh, guess I could makes some jokes right there...but I'll refrain
No worries---and welcome to our club!
