@alex I just remembered this for the first time in a long time:
I was a kid and answered the doorbell. It was a door-to-door evangelist. My family was church-going, but in a kind of melIow way, and I had no concept of proselytizing.
He asked if I wanted to live forever.
I gave due consideration to the physical and mental concerns that might go with such a thing and said "no."
I don't remember exactly what happened next, but he didn't stay at our doorstep much longer.
