Hi Malkavian, The short answer is yes, you can certainly train yourself to be ambidextrous. The task of motor function is allocated to a specific area of the brain called the motor cortex. Since our brains are divided down the middle we essentially have two of these areas. The tricky thing is that the motor cortex on the right side of the brain controls the left side of the body, and vica versa for the left. Now, when we walk, we use both legs equally well, or when we raise our hands both the right and left can do this task equally. The difference becomes apparant when we use fine motor skills, like writing, or throwing a ball. The reason we can throw or write better with one hand is because we trained ourselves to do it that way. Now, there is also a little bit of dominance going on there too. You can start teaching a child to throw a baseball with his right hand, but he may feel more comfortable doing it with his left. Why, who knows? But there is something hardwired in most people that makes us prefer one hand or leg over the other. We can train ourselves to perform any task with the other hand though. For instance, I play the guitar and have to use my left hand to fret the strings while my right hand either plucks or strums. I have a left handed friend who has a lef handed guitar and I can't play that worth anything because I have trained my hands for a right handed guitar. But I am able to figure out where to put my fingers, and with time I am sure that I could become adept at playing the other way. As for how long it would take, that is up to each person individually. Everyone has different speeds of learning a physical task which also depends upon what that task is and the amount of practice. The most important thing is that it is possible with lots of hard work. Good luck, Mark
