Most Jehovah Witnesses family patriarchs and the most ubers ones are mostly baby boomers. I have seen an entire family walk away when the old man kicked the bucket. The interesting part is what is going to happen when the baby boomer start to die in the next 15-20 years. How many people are just hanging around for family reasons.
Mind you I am beginning to think the average might actually be retarded or it is just a social club to feel superior to the average joe.
