Also, I have to agree with WR about being a dad making people faster.
My wife and I do not have kids, nor do we ever plan to have children. But, I have noticed that all of my friends who have children suddenly become super fast. One guy I know had a kid and then suddenly was upgraded to a 1, despite spending like 20 years as a 2. Another guy had a kid, then lapped the filed solo in his first race back. And another guy I know had a kid and started podiuming pretty much every race he did as a 5 and 4 - he podiums less frequently now that he is a 3.
