I've noticed that a striking number of baptisms at assemblies and that are around 16 or under. I was baptised at 19, and everyone just assumed I was 'raised in the truth' when in fact I'd come 'in on my own'. The usual mix seems to be born-in teens and people over 40 around here.
How's this, out of 5 baptised from my cong with me, not one is a JW now. One in his 50s died a JW about a year later from a heart attack, one the same age as me left JWs just after baptism and got dfd, another convert with a couple of kids hung on for a couple of years with the man who the elders made her marry (they were just living together) before she could become a publisher then left said man for another and got dfd, a guy in his early 20s, born in, got dfd and jailed as a pedophile, and all that was left was me, until this year.
