This is not a scientific post. I’m not dropping any science on you. It’s a topic of interest to A Dude and probably to many. Tonight on the way home from an errand, I ran into another bicyclist (he’s OK). Turns out he’s a student at the University of Texas. He was a super nice guy who had just come from a soccer game and wasn’t wearing a bike helmet. He was stopped at the sign near where Anthony Diaz was killed by a bus driver, and I asked him what happened to the ghost bike. He didn’t know, but guessed it was an upcoming marathon.

The immune systems of what the scientists called “non-elite older individuals (master cyclists)” and the younger sedentary ones were similar. Hey I like the sound of that, “master cyclist!”
