Yet another tale of mice and assumptions, as best I can make out. Of course, I'm one of those runners who never gets this mythical (to me) high - even when I was super active (3 runs of about an hour each per week) I hated doing it (tldr - basic running is cheap exercise).
I know people who love to run and talk about the high because they take it for granted all runners have it. Now they can blame my leptin levels!
