There's tons of elderly joggers in my area. It's always so fucking weird to hear that argument from people.They're everywhere! Any area with good parks should have tons of counterexamples to show that it's hardly inevitable. And those are people raised in an era that was pretty lacking in medical knowledge. Anyone with even the most half assed attention to their health right now should be able to do better. But that's the real problem. Even asking for half assed attempts these days is too much.
