A study published in the Proceedings of the National Academy of Science found, however, that people tend to marry someone who has similar DNA to them.

Low cholesterol improves performance in bed In addition to harming the heart, high cholesterol also contributes to erectile dysfunction in men. In fact, this male problem can act as a warning sign of cardiovascular disease. On the other hand, men who take statins or other cholesterol-lowering drugs tend to improve their sexual function.
