If sex is important to you, be glad to know that you're more likely to stay sexually active into your old age, according to a recent study published in JAMA Internal Medicine.

Researchers at the University of Pittsburg distributed annual questionnaires to 354 sexually active women aged 40-65, to assess their sexual function (including arousal, orgasm, satisfaction, and pain), sexual activity, and how important sex was to them over time.

At the end of the eight-year study, more than 85% of the women were still sexually active. Surprisingly, it wasn't the sexual function that made these ladies keep going at it, but it was the women who reported placing a greater importance on sex who were more likely to remain frisky through the years.
