Laugh lines and crow's feet could be more than just a sign of maturity. They could tell doctors how healthy your bones are.

A study at Yale University found that women with more wrinkles have lower bone density. Researchers say skin and bones have a lot in common, such as how much they rely on collagen to stay healthy.

The scientists behind the study say there's a lot more to learn, including whether estrogen therapy could help slow down bone loss.
