The more miles you drive a car, the more prone it is to breaking down or having mechanical issues. I’m struggling to see how constant exercise like daily 5 mile runs doesn’t add “wear and tear” to the body.

You strengthen your body by breaking it ever so slightly, and then the cells respond by making themselves ever so slightly stronger to survive that experience that damaged them. Over time, you become stronger.
A car cannot rebuild and fix itself, so it doesn’t fully compare.
Eventually, when you’re older, your body and cells struggle to bounce back and rebuild the same way it did when you were young
