Mrs Phizzy and I were both born-in, and left in our late fifties, so there is hope I suppose.
I think that most JW's with half a brain are now only in for the two reasons stated above, Social reasons, and fear.
The July study WT may be a spur for some to leave perhaps, and eventually the pointless drudgery and sheer boredom of the religion may push others to fade.
For many a long year the WT has had "hole in the bucket", but the waters of new recruits in the top meant they could ignore the trickle of those leaving. That is no longer the case, the WT is worried.
Their response seems to be a really serious tightening of Control, I fear that as this goes on, it will be ever harder for those still in, in for whatever reason, to leave.
