Elders and ministerial servants are less likely to leave the truth. Appoint them young. On the flip side young, inexperienced elders have the ability to wake up others.
Yes unfortunately it's the lousy elders who get "locked in" by the power and benefits that go along with the position.
The good ones will wake up and leave when they see how wrong /unfair judicials are and the other dark secrets kept from the flock - such as CSA and the cash cow that are conventions/property flips.
They have had periods where young elders, even in their early 20s, were a thing. Most of the congs are women anyways and they've always had to deal with the less experienced telling them which way's up! The only non serving older males will be fed up Pimo husband's, who just want to be left alone😜
