LOS ANGELES (AP) — Want a clue to your risk of heart disease? Look in the mirror. People who look old — with receding hairlines, bald heads, creases near their ear lobes or bumpy deposits on their eyelids — have a greater chance of developing of heart disease than younger-looking people the same age do, new research suggests.

Doctors say the study highlights the difference between biological and chronological age.

“Looking old for your age marks poor cardiovascular health,” said Dr. Anne Tybjaerg-Hansen of the University of Copenhagen in Denmark.
