Sometimes all the pension planning in the world will not allow a person to save up enough money to retire comfortably.  Sometimes a person finds retirement boring and craves the daily structure of a job.  Regardless of the reason, many people who have retired actively look for a part time job to help augment their income and simply get them out of the house.  There are a variety of different jobs available for the retiree, such as greeter at the local Wal-Mart, freelancing on the Internet, selling items on eBay, and even working at the closest fast food joint.  Being retired and working part time is becoming more common and it is a great way to make new friends.
