Left and right

I'm right-handed but I've long realized that I do some things with my left hand. I hold my glass or cup with my left hand while eating; I prefer to pour water from a bottle or pitcher using my left hand; and I type text messages on my cellphone using the thumb of my left hand. Then I carry my shoulder bag over my left shoulder. I also know that my dominant eye is my left eye and that I hold the phone receiver to my left ear. Then while driving home today, I discovered that I actually steer the car using my left hand and just use my right hand to hold the steering wheel steady.
