29-year-olds are more popular than any other age group and have an average of 80 friends - 30 per cent more than the average across other ages.
Researchers found that at 29 years old, humans have an average of 80 friends, which is about 30 per cent more friends than the average held by other age groups (64 friends).
At 29, people are still in contact with school friends while they have also developed some work-based friendships.
The study of 1,505 Britons found that the average person has 64 friends and that they are most likely to meet them at work rather than at college or university, 'The Independent' reported.
The research, conducted by Edinburgh-based food firm Genius Gluten Free, also found that people have more in common with colleagues than they do with old school mates.
This is because people share the strains of working in high-pressured environments and spend more hours in the office than ever before.
