Can you still get stretch marks at 50?

Probably. I know this is a minority view, but i believe stretch marks have less to do with stretching than with increased hormone levels; that's why they are most common in teenagers, pregnant women, and obese people (fat cells secrete estrogen). If you are getting stretch marks at 50 for no obvious reason, see your doctor to rule out a hormonal problem.
