  • So, the rectum (poops last stop before freedom) is actually deep inside your pelvis as your colon makes the turn from the left side to the center, so your massage isn’t moving the poop out like squeezing a toothpaste tube. However, it lies close to some internal muscles like the iliacus which can put pressure on it if they’re stiff or inflamed (not unheard of in western society), and massaging them can get them to relax and relieve the pressure.

    You’re certainly not hurting anything with this, and since you’ve been doing it for so long, you may have developed a psychosomatic connection that might actually help your bowels do their work. It’s weird, but go right ahead massaging the shit out of yourself because it might help in some way.





  • I’m an athlete and a biomechanics student who studies this sort of thing. Technically, if you do the physics, yes, pavement is harder than dirt. Will your body actually notice that difference given the forces that you experience from an easy run in modern shoes? Not likely. For a few hours a day, day in and day out over decades, then yes you will. But if you run a few miles once or twice a week, no, you probably won’t see a huge difference. (And most trails frequented by runners are packed dirt that is not much softer than pavement. Getting onto shift and squishy loam tails isn’t feasible for everyone.)
