Women are twice as good as men at making friends for life.

A study found that one in three ladies say their best friend today is someone they met at school. Men, in comparison, don’t stay as close with only one in six (16%) saying their best friend is from school. And while both men and women may have hundreds of Facebook friends, they say they have, on average, just five real friends they’d call ‘close’.

In a majority of cases, best friends only last half your life and as you get older the number of good friends you have slowly decreases leaving you with an average of just three friends by the age of 60. Adults tend to retain an average of five friendships with people they met at high school, according to the national study with 37% of friendships forming in the workplace.
