When I look back, since I was born in the 50s, I see MOST oldtimers that I grew up are still connected to the Organization. That is, those who were in the 50s and 60s.
Those that came in the 70s seemed to leave, pretty much. The ones that came in the 80s and 90s seemed to be mostly mentally unbalanced and some still go to the meetings but many suffer from depression and are not as active as they "should" be.
Are most of the Witnesses that you knew still practicing or are they gone?
