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.
Funnily enough I'm kinda already doing all those things by accident. I have naturally broad shoulders and a decent bit of both fat and muscle, I have a pretty bushy beard and I wear old man glasses. I'm not even trying to look older, I'm just doing things at random
