10. Happy Downstairs, Happy Upstairs

Sex has all these medical health benefits but at the end of the day, whatever makes us happy makes us healthy. As long as you feel fulfilled where the sun don't shine, you will feel shaper, motivated and energized. So go ahead, open up your body and soul to some  nocturnal (or daytime) fun, because it's good for you!
