... The older you get, the more you can "stretch" the age range you hang out with ...
Can confirm. I'm pushing 50 and have close friends between about 23 and 75.
I also can no longer tell the difference between someone who is 20, and someone who is 40. It honestly doesn't matter to me, and I don't care.
Knowing and socializing with at least 3 generations of people is the key to Perspective.
