35-40 years ago I had to switch to left because of too much strain on the right hand. I was very happy when I found a way to mirror my cursor. Am back to right hand now though.

Just wait until you find out why scroll bars are on the right.

I feel like the scroll bar location has more to do with english being written left-to-right.

Peev: UIs and desktop ebbing that shrink or obscure the scrollbar. Gah, stopit.
