People blessed with youthful faces are more likely to live to a ripe old age than those who look more than their years, work shows.

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.
Apparently it’s not just a function of people looking younger because they are not burning the candle at both ends, so to speak,

A telomere of shorter length is thought to signify faster ageing and has been linked with a number of diseases.
In the study, the people who looked younger had longer telomeres.
And now for a non-sequitur,
