Another Discussion

I have been reading all the comments on my other post and decided to mention another topic. Today I read in USA Today that Retiree Benefits Grow into 'Monster'. Yesterday, I heard a discussion on the radio asking the listeners to list and rank the things which most concern them about the future.
So many things from which to choose: the bird flu, nukes in Iran, the NSA listening to our calls, a tsunami hitting the west coast, the NOAA prediction of another hurricane hitting New Orleans this year, drought, flooding, global warming, global cooling, global thermonuclear warfare...
Some of the things I listed are tongue-in-cheek but all are in or have been in the mainstream media of late.
Being the optimist I am - just ask anybody who knows me - I would like to have a list from you of what most concerns you and why you think (if you do) that we will be okay anyway.
Of course, feel free to continue your discussions elsewhere on this blog. John Galt, I know you will be unavailable for a time, but you are always welcome.
