This is something I’ve wanted to know for a long time, but I’ve never found an explaination of why this happens.
If you’ve never done this before, go do it now:
-Stand in a doorway with your arms at your side
-Hold out your arms so that the backs of your hands are pressing against the doorframe and your elbows are straight
-Push against frame as hard as you can (don’t hurt yourself) for about 30 seconds
-Step away from the door frame and relax your arms
What happens? Yours arms lift up, all by themselves! It’s the strangest thing. I’m sure there’s got to be a medical reason why this happens. Anybody have an explaination?
