I believe I could switch sides, as I was almost equal in handedness earlier in life. I don't know if that's still true. About 30 years ago I was in the trial for Xanax (couldn't take it) and while I was in the trial a doctor wanted to test me to see if I had equal handedness, as that, he suspected, was a sign of depression. I never found out any results from his survey, and I suspect it is bogus. My grandson is left handed and I cautioned his parents, who wanted to encourage him to go with the right hand. It's not an important thing which hand you use, unless of course you have an impairment on one side. Most of my deficits are on the R. side, my dominant side, and it might be well to encourage the left hand to do more things. As it is, I eat with it, cut food with it, just don't write with it.
