As the average age of JW's climbs and many hit their 80's+, I think we are starting to see the number who die each year approach the number who get baptised.
As the conscious class grows and fades away from the WT, and as those who were baptised as children wake up and leave, I think we may have hit the top of the curve already.
2014 passed without incident, downsizing and layoffs are accelerating, and there's nothing left for them to look forward to and get excited about.
