When you fold your arms, the arm on top is the one you are dominant with. Same thing with clasping your hands. Your dominant hand's thumb will be on top. I don't know why that makes it comfortable, though. Except with me, going off of that I should be left handed. Maybe I screwed up as a child, I dunno.
Crossing my arms, my non-dominant arm is on top. Folding my hands, my dominant hand's thumb is on top. Maybe I'm just too cool for genetics
Lol or maybe you use both sides of your brain equally? I think I do.
I'm a righty, but when I cross my arms/fold my hands, it's always the left that's on top. :/
I just tried folding my arms the opposite of how I normally do it. Turns out, you're right!
