Being born in the late 70's pretty much meant that everything cool had already be done. When Jimmy Hendrix was playing guitar with his teeth and lighting it on fire, it was innovative and new. When Evil Knievel was jumping is Harley over a whole lot of buses he was the acest dude alive. But then the whole extreme movement came along and made everything you do seem totally pissweak. Now you have to jump over a ridiculous number of buses before people will care and even then they probably won't because you don't have a name with as much cache as Evil Knievel. Also some other dude is probably doing it with two backflips thrown in.
When everyone was conservative you could be rebellious and shocking. Now you would have to film a celebrity sex tape while going over Niagara Falls in a flaming barrel for people to take notice.
Also all the cool shit that we thought we would have by now just hasn't come about. When they were playing golf on the moon people were thinking they would probably have an 18 hole course up there by now. When I watched Back to the Future 2 I thought I was going to own a hoverboard. It's ridiculously disappointing.
