As noted by many here, since 1995, when the amount of elders has dwindled, the challenge for the GB is how to tackle that problem. One solution was to appoint young men in their mid 20's. As has been noted, many pros for the GB, tons of cons for the congregations who have to put up with leadership from young men who stopped picking their zits a year or two prior....
ATJ - This is such a key point. I was on a body a few years ago, and there was a young Ministerial Servant who was pioneering and had just finished MTS school. His name came up for discussion as an elder.
I was totally against appointing the young man as an elder. He was (barely) 24 years old. He was a total born-in and was thus totally naive when it came to the ways of the world. This young man was very, very smart, but he lived a very sheltered life. I was appointed in my mid-20's and I had to sit in meetings that would make a sailor blush There was NO WAY I felt that he was ready to be an elder! Sure, he could give excellent talks, was a great speaker, etc....but what was he going to do when he was sitting on a committee dealing with serious personal issues? All he was TRAINED to do was either reproof or disfellowship - he was not equipped to ponder over such deep things and realize he was dealing with a REAL person across the table..... (Of course, even old, experienced elders often fall into the same catagory.)
The rest of the body agreed to wait to appoint him- for HIS sake. Sure enough, we got a letter back from the branch stating that unless there was an OUTSTANDING reason why not, he should be appointed immediately. Needless to say, he was appointed ASAP. The last time I saw the poor guy, he looked like he had been run over by a frieght train. Based on my experience and many others, I think elders age in dog-years!!!!
