It's probably a little late for most male Gray Iron readers to do anything about it, but recent studies indicate that having four or more children increases the likelihood of living to 100.
Wow! When I read that headline I thought it sounded a little goofy, and if you read my blog regularly you know that I am generally suspicious of many claims that are supposedly backed up by "scientific studies." That's why I like Snopes and junkscience.com, incidentally. It is B.S. not hydrogen that is the most common element in the universe. Still, many studies are of course truly scientific, important, and valid. Either way, valid or not, this one is an interesting read.
