When I first started biking, I'd be really careful and focus on how I'd feel a bump in my head. But after a while, and as a ride progresses, I sort of get in a happy zone of being in the moment, still being careful to not hit big potholes, but just enjoying exercising, and I don't feel the bumps as much as I did early on.

So yeah, I think a lot of it is probably in our heads.
