Two people sharing lives together, who both have a good sense of humor, are significantly happier than those couples with a poor sense of humor. Humor can act as an emotional release thereby releasing stress and promoting longevity. It also allows us to cultivate and keep friends, support groups, and perhaps even love, and love heals. You want to be with someone who makes you smile and laugh. To me, it is the definitive personally trait that makes being with someone over time possible.

Laugh, and the world laughs with you; / Weep, and you weep alone; / For the sad old earth must borrow its mirth, / But has trouble enough of its own. Solitude by Ella Wheeler Wilcox
