Even talking on the phone or texting does not make people feel as good as sharing a smile, the research says.

People find the most satisfying relationships come from a small number of close friends, with an outer "ring" of 10 significant others.

People communicating face to face on Skype were 50% more likely to laugh, and they rated themselves as significantly happier. Dr. Roberts's finding that there was no connection between Facebook use and people with many friends was  _
