I grew up in the 1980's, and heard the exact same thing. I'll never grow old. I'll never get thru high school, much less graduate from it. I'll never have to worry about a job, a mortgage, or kids in this "System of Things."
I did all of that. I am 37 next month. I have white hairs. It's been really hard for me coming to terms with the prospect of growing older. My grandparents and parents have all passed away. All of the "older ones" in the Congregations I grew up in passed away. So did one of the congregations!
The WT is like Satan in the Garden of Eden, claiming, "If you just peddle our crap and keep giving us your time, money, and life, you'll NEVER die!" Sick, twisted, liars.......all of them.
