After retirement...is there a life?

For some, its eagerly waited. For others, its a dread. For some, its totally unplanned and can even be unexpected. For others, its just the passing of a phase in life before going on to another which can be just as exciting if not more. For some, its waking up in the morning and not knowing what to do. For others, wow! its freedom! I don't have to go to work anymore! For some, its the feeling of being unwanted and unappreciated. For others, who cares! I now can live the life I want.
So, what it's like to retire? Is there life after retirement? I wonder myself!
