He is the product of a breeding experiment by the biologist Ted Garland, who selected mice for the tendency to run on a wheel for 70 generations. Garland speculates that Dean is physically addicted to running—that he gets a dopamine surge that he just can’t get enough of.
Addiction theory long ago embraced the idea that behaviors such as exercise, eating, or gambling may have similar effects on the brain as dependence-forming drugs such as heroin or cocaine. I have no beef with that, beyond irritation at the tenuous link between a running captive mouse to a human junkie. What’s troubling here is the genetic determinism. My argument is about language, but it’s more than a linguistic...
