This is incredibly insulting.

That's not how it works for me, sadly. After a good run, my mind still wanders, I literally daydream about random stuff for up to an hour (or even more)...

I hope other people have a better experience.

Have depression? Just try being happy.

Have ADHD? Just try focusing.

It would be more helpful to phrase this as “For me, I find running for an hour really helps me focus immediately afterwards”
