It was really strange when he had gone nearly 3-weeks without posting. I think it was a first, and that suggested that there was something serious going on. He had not gone more than 7 or 10 days without posting in 10-years from what I had known.
He has as good odds as anyone in this challenge. He has access to the greatest doctors in the world, he can afford any kind of treatment, and he's smart enough to make informed choices and take charge of his treatment. I really wish Zeev the best.
