I think what you're getting at is: "does using our body also age it?" It's complicated but I recommend you read up on Hormesis: https://en.wikipedia.org/wiki/

I think what you're getting at is: "does using our body also age it?" It's complicated but I recommend you read up on Hormesis: https://en.wikipedia.org/wiki/Hormesis https://en.wikipedia.org/wiki/Hormesis Cells have thresholds for what's considered to be a "good" stressor or a "bad" stressor. Alcohol was thought to be hormetic for a long time (though, it maybe/probably isn't?) as it was thought that low doses could be beneficial with high doses obviously bad. Exercise is thought to be hormetic and there's quite a lot of research supporting that.
