Glad you asked! When I get edgy about being old I simply listen to the grateful dead.  Its not my favorite band mind you but it represents my generation and how powerful it is (was)Last of the baby boomers here! 
I dont like the fact that the body breaks down so eaisily but I love the fact that Ive so many "experience points" on younger folk. Sure they are higher tech but I know enough to get by on my own.  Ask a teen how long they could last living by 1972 standards and you'll get a good laugh because they wont have a clue.  Makes me wish I listened to my folks more about living in the 40s.
I asked my older brother the other day if we were now old men..52 and 55.  He said, "your younger than the mountain but older than a head of lettuce 

 Kinda made sense somehow that its all about attitude.
