61 yr old runner here. I've been running since 1990 & look like hell. Decades of exposure to the sun, wind & all other weather elements has really destroyed my skin. People mistaken me for a 70 yr old all the time. In fact, on the dating app that I'm on, I get a lot of likes from 70+ women. Lol.
I have a lady friend who's in the same boat. She just turned 50. She's a life long marathon runner & loves being in the sun. She's often mistaken for being a 60+ yr old woman. Her face has aged dramatically & she looks pretty rough. This is the kind of woman that from behind looks 30 (nice, long beautiful hair...fit, trim, sexy body), but when she turns around - look out! 😯
Legendary runner "Raven" looks really beat up from over 4 decades of running. I don't know how he keeps going:
IMO, compulsive year-round will make you super physically fit & yet accelerate aging all at the same.
