It can be a distressing thought that finishing your working life may mean an end to your work based social life.
However, retirement doesn't need to be a lonely place. In fact if you think through your interests and passions, perhaps with the aid of a retirement coach, you can quickly meet new people online. Facebook, Twitter, even Friends Reunited as well as specialist forums and networks open up a whole new world of friendships if you want them to.
Action step: Why not have a quick Google and see what networks you can find?
