What Is My Handedness?

My parents say I alternated handedness as a baby, so they just started teaching me everything with my right hand. I've only recently noticed, I do different things with different hands. For instance, I write with my right hand, but I can also write with my left when using a blackboard or whiteboard. In baseball, hockey and golf, I bat shoot and golf left handed. I cut food left handed, I can throw with both hands, kick with both feet and when hitting something, I tend to favour my left hand.
