Ok ok ok, I shouldn't say "I feel old".  I gave a dirty look to a guy next to me at the pool over the weekend, who said, "They were 4 when 9/11 happened. I was in 5th grade! I'm so old!"  I was much older than that. 

ANYWAY, unless you're one of these kids, you'll feel a little - aged - when you see how they react to a Walkman.  PS - I lost all faith in humanity at 1:55 in.
