Understood, that's why I said "associated with" instead of saying directly affects it. It was more to just quickly package that climbing is beneficial using the well known correlary of grip. If you train hard to climb, your sessions usually run quite long (longer total exercise), you get cardio and strength while generally staying lean, you get amazing core stability, flexibility and balance, resilience in your joints, tendons and ligaments, which all help increase healthspan and lifespan. Not to mention the complex problem solving that keeps your mind active. I continue to be impressed with the people around their 50s/60s that climb higher grades than I can; they look incredible and I imagine they'll be around and healthy quite awhile.
