Who needs a new life? I'm 65. Left the workforce at 44 to persue varied other interests. I don't travel but have been involved in many activites. I'm not intererested in self-gratification so much as in being useful and productive. I place a high value on personal freedom. The philosophy is constant while opportunities and interests change. I don't need anyone to define or to fulfill my life or to" start it over".
I agree with the above philosophy as well. Since retirement I have a nice home, dog, yard, and unlimited opportunities to expand my interests. I don't need anyone to "start a new life" for me. I just enjoy the people who enter my existing life.
