Dave, off topic but that's never stopped me before.

My eldest daughter really took to maths. She was learning, understanding and applying calculus at the age of 15. I'm mostly sure how to spell it, the history of it and even some uses for it. But edo it? Not a chance. I can keep a running estimate of groceries and their total cots and usually I'm out by a percent or two on $100 dollar shopping days. That from a guy who has grade 10 despite sitting through a year of grade 11. This has led me to conclude that genetics is a black art.
