A switch hitter
Since my days in school I have thought I was left handed, doing things right handed sometimes felt wrong to me.
Today, not only starts a new year for me, but probably a new way of life as my right hand joints are so badly damaged I am forced to use my left hand more than I usually would.
Until recently - within the last 20 years - if you were at school and tried to write left handed you were punished. In some religions to this day, being left handed is considered as a sign of Satan.
