I'm a lefty and my husband is a lefty and one of my son's is a lefty too.
My oldest brother is a lefty too, So that's 3 out of 5 lefties in my house now and 2 out of 6 when I was a kid.

Karen, you are right about more artists being left-handed.
Usually lefties are about 10 per cent of the population but in my college art classes the ratio was 50/50!
Two of my favorite artists are lefties, Da Vinci and Michelangelo.
Here is a link showing other famous lefties, scroll down it's a long list.
