According to WiseBrother.com:
A behavioral psychologist in the U.K. named Robin Dunbar just shared some new research into how many friends we all actually NEED. And he says we definitely need some . . . but we don't have the emotional capacity or energy to handle too many.
Here are the EXACT numbers you need, according to what he's found . . .
1. You need five best friends . . . that's someone who'd give you a kidney.
2. You need 12 to 15 supportive friends . . . those are people who'd be really upset if you died.
3. You need 50 good friends . . . those are people you'd invite to a big birthday party, but maybe not a small dinner party.
4. And you need 150 regular friends . . . those are people you're happy to see at weddings or reunions but don't keep in touch with all the time.
