I have a left-handed mouse as well (which really screws up the IT guys when they have to work on my computer, LOL!). I really, really want to get a wireless ergonomic keyboard with a wireless left-handed mouse, but apparently nobody makes them. I don’t get why such an significant part of the market is being ignored.
The areas where things are a little dicey for lefties is using a circular or jigsaw (the sawdust comes out on the wrong side right into your face, or the blade protection is on the wrong side), and driving a straight stick where your non-dominant hand is used to shift the gears. I’d probably LOVE driving a stick in Britain.
Dyslexic lefties UNTIE!
I’m an admin and have answered phones most of my career and they all are designed for Right Handers - the receiver is always on the left (they assume you’ll pick it up with your left hand so that your right hand is free to write down anything of importance)...
When we were in Ireland, my right handed husband and son would not let me drive. I think that they were afraid I would take over the world if I was able to shift with my left hand. hehe.
