Danish scientists say appearance alone can predict survival, after they studied 387 pairs of twins.
The researchers asked nurses, trainee teachers and peers to guess the age of the twins from mug shots.
Those rated younger-looking tended to outlive their older-looking sibling, the British Medical Journal reports.
The twins were in their 70s and older. The younger looking ones had longer telomere caps on their chromosomes.
In the study, the people who looked younger had longer telomeres.
The telomere link to life expectancy isn't surprising. Also see my posts Telomere Length Indicates Mortality Risk, Chronic Stress Accelerates Aging As Measured By Telomere Length, Telomeres Shorten Quicker If You Have Less Vitamin D, and Sedentary Lifestyles Age Chromosome Telomeres Faster.
