Even if this line is true, and I am not saying that it is, running and other cardiovascular activities lower your resting heart rate [1]. So even if you believe that you only have a finite number of heart beats, running should in fact increase your lifespan.

Unless you die on a trail run from a heart attack

(This has happened to two family members that were both runners.)

Generic heart disease runs in the family. Every male in my family basically dies of it, it doesn't matter how fit they are or how much they lift or run. Hasn't mattered. This goes back 5 or 6 generations.
