I'm primarily right handed but have been training my left hand over the years, you should see me handle two butterfly knifes at the same time. Working at KFC, I've found that I often have to use both of my hands at once, I'm glad I've been training my self to be ambidextrous. My mom is left handed, and a few years ago our kitchen caught on fire and she burned her left hand. She was able to train her self to use her right hand and that gave me inspiration to teach my self to use my left hand. It has helped me alot in what ever I do. My mom has told me stories about how she fought with her school because all of the desks were designed for right handed people back in the day. And today, I see that alot of tools are designed for right handed people, which I think is crap.
