Why Your Friend Circle Changes In Your 30s
The expiration date on friends
Research has found that your friend group will go through some major turnover roughly every seven years. Participants were surveyed at the beginning of a seven-year period and at the end of it, and reported only having around 30 percent of the original friendship group from the start of the trial period. The research does say that the simple ability to be near each other and often (like at work or school) was a major predictor of the success of a friendship.
