This kind of head-above-water happiness is unstable and easily disturbed. Our partner will buckle under the strain of holding us up, and big waves (such as failures at work or criticism from parents) will wash over us no matter how hard our partner works to save us. Our culture offers many other life preservers—television, social media, shopping, working, smoking, legal and illegal drugs, alcohol, pornography, prostitution, plastic surgery, diets and exercise, fatty and sweet foods—all the common addictions.
