Retirement in the 21st. century is a new concept. The transition from full time work to full time retirement is a new stage in life that may take many years. It is time to start imagining your life with a thirty year bonus!
There is no model for current retirees to follow because there has never been a time in history such as the one we are presently in.
Traditionally, retirement was seen as an ending of one's functionality leading to a life filled with empty leisure. This certainly was a boom for the leisure industry. Now, this plan no longer works financially for most people or is enough to give life purpose and meaning.
