Younger people today are in terrible shape compared to students in school during the 70's and 80's, I see it every day. Times are different though, too. kids used to kill time playing street ball or just being outside and doing stuff that was physical, not as much any more. I remember Atari and Intelivision and the start of video games way back when, it was kinda cool being a new thing and all that, now it has helped to create a society of wimps.
I talk to recruiters all the time at school and they tell me that if we ever fought a large scale infantry type of war again we would get killed because kids today are sissies, not all of them for sure, but TOO MANY. Our technological edge is what keeps us still top dawg, not so much the "greatest generation" thing anymore- they might be right ?
