Writes Magdalena Taylor, in a guest column. Sex is good, sex is healthy, it is an essential part of our social fabric. It is a critical part of our social fabric, but in the midst of a loneliness epidemic, we are not having enough sex. It is a critical part of our social well being. Less time is spent with friends and lovers, in isolation that is limiting social lives and happiness. Sex reduces pain, relieves stress and makes the heart stronger. Sex is an act of social solidarity. Any capable person must have more sex, as often as possible.
