The Winnipeg Free Press this morning reminds us of some of the ways in which sex, besides being fun and feeling good, is good for us.

* Having sex three times a week can make you look a decade younger than you are. (Though we’re assuming this doesn’t kick in until your 40s or so, or it might be kind of creepy.)

* Sex can boost your immunity—specifically, raise your levels of immunoglobulin A (IgA), an antibody that can prevent the cold and flu. (Funny how doctors don’t tell you this unless they’re dating you.)

* Men with "high orgasmic frequency" have a lower mortality rate compared with men who had fewer orgasms. (So if your partner is telling you he might die if he doesn’t have more sex with you, science is backing him up.)

* Of women who tried sex while having a migraine, 30 percent reported some pain relief from having sex and another 17.5 percent ended up completely pain-free. (This looks like a small sample size, and we note that the other side of the coin is that more than 50 percent reported no change or a worsening of symptoms. We’re thinking the odds are still against it being a good idea to pressure a partner with a migraine into having sex because “it will make you feel better.”)

One of these days we want to see a survey of what scientists think about sex, because it would be just great to turn the tables and study them for a change, don’t you think?
