Dr KimIf you are right-handed, have a go at writing with your left hand to see how hard it is for a lefty to write neatly.
All of us have to learn to use both hands for some things. When you are old enough to drive a car in Australia you have to change gears with your left hand even though you are right handed. You need to use both hands to be able to type properly. You need to use both arms to give someone a hug!
