You can expect to make 363 mates during your life but you'll only be able to call six of them your true friends, a survey has found.
Ten thousand people were quizzed to find out how we make and break friends.
The results showed that most of us will end up with a circle of about 30 close friends, with six of them being the ones we tell our innermost secrets to.
The poll also revealed that many people keep in touch by text and e-mail rather than by talking to their mates.
