Exercise and sex are intimately connected to each other and to our world. They are the oldest physical activities. Both are integral to human survival. Long before the beginning of modern civilization, our ancestors ran through woodlands and prairies, chasing wild animals to feed their families. Running, especially being able to run far and fast, was very important. Without running, there would be no food for the family. And without sexual intercourse, there would be no future family. Research has linked both exercise and sex to many health benefits, such as decreased blood pressure and lower risks of cardiovascular disease, diabetes, depression, and obesity. Studies also show that body image, which is enhanced with exercise, plays a key role in sexual desire and satisfaction. The fact is that exercise and sex are good for you, in many more ways than people think. And the more of each you get, the better. Sex and exercise connect us to our bodies. The human experience is a physical one, and sex and exercise are the best expressions of our physicality. To live life fully, we must fully live on a physical level. Sex and exercise are so intimately connected to our bodies that a lack of it hurts our physical health. Sex and exercise are the best physical expressions of who we are, arising from the same primal source.
