What age do we hit ‘peak friendship’? Scientists believe they may have found the answer.

There is a specific age when a person will be at their ‘most popular’, according to new research, with the amount of friends we have decreasing once we are past it.

Our social networks shrink from the age of 25, the data reveals, with the pool of friends a person has getting smaller and smaller as the years go by.

The phone records of more than 3.2 million mobile users in Europe were analysed for the study by researchers at Aalto and Oxford universities.
