. . . A ten-year psychology study undertaken in Germany during the 1980s found that men who kissed their wives before leaving for work lived, on average, five years longer, earning 20 to 30 percent more than peers who left without a peck good-bye. The researchers also reported that not kissing one’s wife before leaving in the morning increased the possibility of a car accident by 50 percent. Psychologists do not believe it’s the kiss itself that accounts for the difference but rather that kissers were likely to begin the day with a positive attitude, leading to a healthier lifestyle. . .
There you have it: permission granted to pucker up each morning, it might extend or even save your life.
