More on my brother... he is determined to continue his loyalty to the WT until the end... of his life, but it's obvious that his zeal to preach is gone. He is just continuing an old habit, Sunday preaching for an hour or two, attending most meetings and all the assemblies. And his more recent goals, as he indicated to me, are to stay healthy by eating well and religiously going to the gym every morning, enjoy life by spending lots of his free time with his wife, and help his two adult sons with their new enterprise in which he is investing a big chunk of money and plenty of time... but he "will never abandon Jehovah".
This is a new breed of JW's, even more strange than the previous one. It is more die-hard loyal to the borg, but more willing to attend to "Satan's temptations", and quite uninterested in doctrine.
