Happiness+1

Happiness 1: hug

 * Students at Pennsylvania State were assigned to two groups. The first had to hug others at least 5 times a day over 4 weeks: front-to-front, non-sexual hugs using both arms. The others did not.
 * The huggers (averaging about 49 a week) became much happier
 * The guys who found it uncomfortable at first found ways to start, such as with success on the sports field
 * Later, the researchers found winking and complimenting also work
