I am classed as left handed as I prefer to write with my left hand, I bowl left arm, use a badminton or tennis racket and scissors in my left hand and tend to punch southpaw.

I shoot, bat, swing a golf club right handed, but a lot of things are just whichever hand is most convenient at that moment.

We had two PCs side by side and I could use a mouse in each hand for tasks such as transferring files between the two.

I use a knitting machine and am fairly ambidextrous on that, after 40 some years, as there are numerous occasions where the same thing is done first on one side and then the other of the knitting. People who are strongly one handed find it more difficult as they try to use the same hand to work in opposite directions. The mirror image is the easier option, but I find it surprising that some people I teach will not even attempt to use both hands.
