Done.

All right.

So imagine the shin bone is like a busy highway, and every time you go for a run, each stride is like another car going over the surface of the highway.

Uh, and we use, like, a Toyota Corolla, um, as an example for the cars that's driving over the highway.

Lots of them, repetitive.

For runners, sometimes it's over 10,000 strides per run, up to 10 times a week.

So lots of cars going over this highway.
