February 27th, here. I was born about 2 weeks late, apparently (Which means I should had been an Aquarius if I was born on the 'correct' date.)
I use my right hand for most stuff, including writing, drawing etc.
But oddly enough, I'm a little stronger in my left arm, so I don't get as exhausted carrying stuff when using it.
Recently, there was a news report on TV about ADHD statistics, about that most children born with ADHD had their birth months in the later part of the year; September to December, or something.
Maybe there's something about being born during the 'cold' months.
