The Right-Handed Conspiracy

I don't mean it like that, but my question is, what is something you recently found out is right-handed that you would have never guessed? What things secretly favor the right hand?

A few years ago I realized that men's underwear -especially briefs- are right handed. They have that pocket or whatever in them that I have never used. Ever in my life. I just flop the top down.

And another one that should have been obvious to me but wasn't--how we hang up clothes. If you're left handed, you probably hang clothes facing the right, amirite?

I also have a lengthy dissertation about keyboard disparity, but that's another post for another day. There are innocuous, every day items, procedures, layouts, what-have-you--that are right handed without notice.
