It seems like it would be true.
Edit - Yep. Per this study:
"Perceived age, which is widely used by clinicians as a general indication of a patient's health, is a robust biomarker of ageing that predicts survival among those aged over 70."
“If a patient looks older than their years then perhaps they should be more concerned," he said.
Good to know I’ll die by the time in 30.
Without actually reading the study (what am I, a nerd?), a serious confounding variable could be prior drug use or some chronic diseases. Both can make you seem visibly aged due to messing with the makeup of your face, basically degrading fats and connective tissue. But the real health issue would be the drug use or disease, not appearance.
The telomere stuff would also align with this, as many hard drugs will shorten them.
