I think he's correct, in my cong we have almost twice as many elders as MS's and the majority of the elder body is under 50. In fact half are under 40. I noticed a trend towards many elders currently in their 30's and 40's.
The reason I think is in 1995 these now 30's and 40's elders were pioneers and MS's and we were all reaching out and pioneering or going to bethel because...... THE WORLD WAS ENDING BECAUSE THOSE WHO WERE PART OF THE 1914 GENERATION WERE FREAKING OLD! Now there is no desire to expend yourself in anything WT. After 1995 most childeren from that time period grew up and went to college or got married and had kids and went to work. Really if you think about it I am correct. Thats why there are a bunch of very old elders and many in their 30's and 40's. As far as MS's you can forget about it.
