As a generation Xer, and child of the 80's, I have to vehemently disagree with this statement.
As a child of the 50's growing up on air bases, hearing the alert klaxon sounding every couple of weeks and knowing everyone I knew and loved might be vaporized in the next 15 minutes; I have to say, you can get used to a lot of bad stuff. Life is still worth living.
There are still ICBMs pointed at us so the terrorists thinking they will back us down with death and destruction haven't really learned their lessons.
