What's FUN when you're 70?  Sitting with a group of friends after a huge shared Christmas dinner and singing carols?  Walking the beaches on Anna Maria Island?  Sitting at my computer for hours doing "work"?  Visiting son in Colorado?  Living in a house at the end of the rainbow?  Hitting the road with the motorhome?   Think I've had fun all week, and even going for a walk in the sunshine might qualify.  Is "fun" what we make it?  Or should I be working harder to organize my time to focus on fun?  Would love your input!
