I am 56 and consistently throw those things in the trash. The whole idea is creepy. First, I don't want any group to speak for me. Second, they seem like a bunch of old people.
My DH (who is 3 years younger than me) wanted to join for the discounts, but after a couple of years of their annoying pitches, he threw the stuff in the trash, too.
We haven't received anything from them in quite awhile.
