World Wars & Vietnam. Just looking at a small section of the US, we have a whole class of High School Seniors that has no idea what will happen with school. Not just Senior Proms, but graduation, GPA's (will they count 1/2 a semester or just cut it off at the end of last semester), starting college next fall, mission service. I know that this is a time that my oldest son will be telling his kids and grandkids about.

Getting drafted straight out of high school into one of the Wars is a whole other level of uncertainty and anxiety, but 9/11 didn't shut down the whole country. This is going to have some lasting impacts, hopefully not hundreds of thousands of deaths and hopefully the economy will recover quickly.
