Yes, we’re talking about sex. We’re also talking about academic research, in this case at the University of Toronto Mississauga, where scientists have determined that sex is good, and more sex is better. But how much is just right? HealthDay reports that the Canadian researchers studied the results from a survey conducted in the United States every other year between 1989 and 2012, focusing on responses from more than 25,000 people, aged 18 to 89. Among other things, participants answered questions about sexual frequency (from not at all to four or more times a week) and their perceptions of their happiness. Ready? The envelope please….The researchers found that couples who had more sex were happier, but well-being leveled off once couples reached a frequency of about once a week. Note well: people who had sex more than once a week were not less happy, they just didn’t get happier with more sex. They just had more sex.
