Do Cougars Have the Smartest Kids? -- New York Magazine

This Old Sperm

Science comes down on the side of the cougar.

Earlier this month, the journal PLoS Medicine analyzed data from a study of over 50,000 pregnant women and came to a simple but stunning conclusion: Older fathers have dumber kids. The more geriatric the dad, the dimmer the progeny, on measures including “thinking and reasoning, concentration, memory, understanding, speaking, and reading.” (Luckily, geezer offspring had no problems with motor skills, making them ideal for wheeling around their elderly dads.)

It was another unsettling addition to the growing pile of evidence that men have their own biological clocks, with older fathers also producing higher rates of schizophrenia and autism. But what really caught my eye was the secondary finding, which was that older mothers were associated with smarter children. I quickly did the calculations and was pleased with my findings. The most intelligent children, I deduced, must be the outcome of 45-year-old career women inseminated by their 21-year-old personal trainers.

At last, science has produced the case for cougars.
