How to be single and happy
Consider the health benefits of being single.
Being single is associated with a decreased risk of adverse health effects from dysfunctional marriages or intimate relationships. Some studies have shown that bad relationships can actually make you physically unhealthy.
But singles are more likely to be fit and healthy. Singles also tend to go to the gym more, eat better, and have lower stress levels.
