I am a father. 2 times. And your graph is the best I ever saw about being a parent. Not that I saw many many graphs on the subject before today, but still, it's the best by far and I doubt anybody will produce a best graph in the years to come. Not sure about the colors tho. :) Thanks for that lovely piece of writing. And congratulations for the 3-soon-to-be-5 of you. p.s. Two video cards, two girls. Coincidence?
