Since work is such a prominent aspect in many people’s lives, it may be one of the primary sources of socialization, particularly for people who do not spend a lot of time with family and friends outside of work. Many retirees who choose to go back to work go into jobs which involve a significant amount of social interaction, such as service jobs. This allows them to keep up to date with social circumstances in the world and to build up new friendships even as older adults. Socializing is an important aspect of life, as humans are very much social creatures. Additionally, having a range of ages in one workplace can allow for a greater variety of perspectives for important discussions and decisions.
