JayMatt19; I’m a lefty (sort of.). I Do write with my right hand, and , consequently put Tefillin on my Left hand. Which made my father A”H happy. (Sparing the embarrassment of his son putting Tefillin on the right hand.). A hammer, scissors or a knife in my right hand are like hanging them on a lamppost. I have zero control. A pen, a screwdriver and a saw are better controlled in my right hand. A spoon or fork, I can handle with both, right and left hand. Even though, I prefer using the left. The only serious consequence of my leftiness was in summer camp where I bumped into the guy sitting next to me. The solution was, to sit me at the (left) end of the table.
If we want to do Scientific research we could inquire why in my family it skips a generation. My Grandfather was a Lefty. My Father was not. My children are not. Some of my grandchildren are. Each of my (married) children have one child who is left handed.
