Boredom, not enough money to pay the bills, unexpected medical expenses, more aches and pains (getting older), feeling out of touch with the working world, hanging around with "old" cranky people like me.

Admittedly I can fix most of these issues with a bit of imagination.
But that would require some thought and work. Something I don't really want to do in retirement...lol !!

For instance: Volunteer work with young people would probably fix three of the issues above.

Just a few thoughts. Did not want to let the cons area of this thread go completely unchallenged.
