I've been left handed for 48 years
But some things I do left handed and other things I do right handed.
Usually, anything that takes one hand I will do left handed, but things that take two I'll do right handed. So I'll hold a knife in my right and a fork in my left - but when it comes to dessert I'll hold the spoon in my left. I'll hold a hammer in my left hand, but a power drill in my right.
Some things I can do with either hand - like catching a ball or holding a bat - but I can only throw with my left.
My writing is atrocious - I was taught to write with an ink pen but when you're left handed it smudges it instantly. That's why God invented computers and printers
