You don't know what you missed! Creativity as opposed to sit back and watch. Write a letter, rather than type an e-mail which will disappear into the ether eventually, unlike a letter which is kept for your Great Grandchildren to read.

Fresh air and sport - instead of computer games and bullying each other from behind a monitor.

That kind of stuff.

I think lots still indulge in what you consider 'old' ways - and they are usually amongst the achievers in this life. ;P
