Re: Mice and carpal tunnel
"You're supposed to lay your fingers _along_ the buttons and _squeeze_ them, not tap with the ends of your digits."
That still doesn't save you from keyboards, whose keys are so small the ONLY way to use them is to tap. Thus why CTS predates computers. People tap mice because they tap keys, so the fingers have a habitual curve to them. Not to mention the curve makes it easier to make an intention whether or not to double-click.
