The old geezers and widows I know are still strong in their faith to the best of their physical abilities. I think the group who is the most bitter is the 40s- upper 50s because they are at the point of life where they feel they got screwed and must figure out how to support themselves financially. Your at the age where you have no skills, if you go back to college your competition is a young twenty-something who the company might view as a long-term asset where HR will view you as ???? Your forty-nine years old and you have experience of a janitor or window washer, what else? "Well, I know how to speak in public, go up to people's house with a message that angers them!"
Let me revise this, age bracket of anger and sourful bitterness 38-57 because you are screwed if you have no education and put the Truth first in your life. The time to get your education age 38 to 44 "Master's Degree" and look! Your considered as one poster put it "The Old Age of Youth!". It might surprise many but the elderly are just as fisty as "Mouthy" and many do have a outlook that is bright even if they are going to die. It's our age bracket that has the most bitterness. We are bitter things are the way they are and our age presents a great challenge for relying on the Watchtower Society's horrible "Life Planning Guidance". I visit plenty of older JWs who are left behind from the Shepherds Of the Flock, and they are only angry at the lack of visitations made to them in their rest-homes, they think "The Faithful Slave is wise and discrete, it's those bad people in the flock who left me to rot in this cursed place. If only the other Witnesses would pay heed to the solid advice of our fellow slaves!"
You probably have a different demographics than I do, so I post what I have encountered.
