I have to laugh. No it’s not. It’s not like healthy people just from the fact that they are healthy have some odd quirk of occasionally randomly tripping into a 30min run without any say in the matter.

Regular running causes an improvement in health.

Improved health does not cause regular running.

I'm a life scientist: it's true that physical exercise has a causal effect on positive health outcomes. However, if you believe demonstrating cause is simple, you don't know enough about science or statistics. It's extremely difficult.
