Although I do not have the numbers to back it up like you do, the same can be said for here in the middle of the U.S.A. I know for a fact that the Elders had a sort of "pep rally" to get the younger men interested in "reaching out" for positions in the Congregation.
They just can't find the young men around here to take the lead. The young men are too busy trying to provide for their families. And what little time they have left is for recreation, not JW activities. Before I left for good, the Elders were even begging me to shave my beard so they could use me. My response was, "It is your problem if you can't use me with a beard."
Shame of it is the average age of Elders around here has got to be 55 or older. In the local Congregation they have 1 in his mid 80s, 3 in their mid 70s, 3 in their 60s, 1 in his 50s, and 1 who is about 40 years old.
Not too good for them.
Is this a light saber in my pocket or am I just happy to see you?
