what now?

what were they thinking?  when you get to a certain age:  no goals left, kids grown, been a leader, been a follower, had successes, had failures, and now nothing left to look forward to but eternity.  what do people think when they reach the end of their middle years and sit at home and stare at the walls?  help please!  i'm lost without a goal, a reason to get up the next day, a purpose to want to really live.  what do people think when they travel, buy expensive objects, have more money than they know what to do with, but still are lost and unfocused?   what happens when no one is there that really cares about you anymore, especially as a couple? kids are grown and living their lives as you once did.  all the people you served and listened to and cared for and laughed and cried with. i guess it's as a movie line was once stated: "death is the greatest and last adventure".
