Rates of sexually transmitted disease have doubled in those 50-90 years old.

According to the editorial, an estimated 80 percent of 50- to 90-year-olds are sexually active. This activity has contributed to rises in cases of syphilis, chlamydia, and gonorrhea among 45- to 64-year-olds in the U.S. and the U.K.

According to CDC estimates, there were almost 900 cases of syphilis in 45 to 64-year-olds in 2000, and in 2010, the number grew to more than 2,500. In the elderly age group, 6,700 people were diagnosed with chlamydia in 2000; by 2010? 19,000.

Well, men think about sex just about as often as they think about food and sleeping.

And while women don’t think about sex as often they are not far behind men. And thoughts of food and sleep are proportionately less, as well.

“The story about this paper that’s been reported in the press has been ‘Men think about sex 19 times a day!’ ” said Terri Fisher, a psychology professor at Ohio State University at Mansfield, and the study’s lead author. But that isn’t all that much when you consider the study’s participants were college students, those repositories of raging hormones and unfettered urges.

“The more interesting finding is that male college students think just as much about food and sleep as they do about sex,” Dr. Fisher said.
