Older fatherhood isn't all bad: testosterone rates drop about 1% per year as men age, making them less reactive and more patient, and a professionally established middle-aged man is likely to have more time and money to devote to his kids than a twenty-something who's just getting started.

In both children and adults, there can be a hard-to-deny link between a robust sense of hope and either work productivity or academic achievement.
