I am left-handed and I have fully adapted to the right-handed world. I can use scissors with my right hand (but not with my left!!) and I have no problems with door handles. I play badminton right-handed. Tin-openers, though challenging, are my friends. But--- I own a left-handed ruler and cheque books present me with huge problems. Fountain pens, though loved by me, cause chaos on my papers.

Here's my real question:
As a left-handed computer user, do you have any problems using your right hand to manipulate the mouse. I'm cool with both left and right (yeah! big tough me!) and often swap hands mid session. What about you? I'm up for a competition.

Ha, interesting question! I'm good with everything..but a mouse and a pen! I can manipulate the mouse righthanded, but not as well as I can with my left.

Now...put me in a sporting event and it's a whole different ballgame!

Dominant right hander here, but I shoot pool and guns left handed. Use to play soccer and can use either foot just as well. I do about 50/50 on the mouse.

i am lefty for everything but......

kicking
mouse (not bad with my left though)
rifles (but not handguns....go figure)
bowling (sucks anyway)
pool

I'm a lefty myself, but I use the mouse right handed. I guess it's because the first time I ever had a mouse there was no way to make it go left handed, so I just got used to it.

I am right footed, however.
