Ned, I've never met you, but your words today moved me. You remind me of a man who was instrumental to me in regards to my life's direction. He has had to deal with just about every health problem that I can think of and has never quit. I was speaking to him several years ago when he was in real bad shape and he asked me, "Who's going to do all this kind of work after I'm gone?" I thought about it for a while and I told him, "to just think about all of the individuals that you have unselfishly shared everything that you know." "That's who."
No worries Ned, sounds to me like you have touched a lot of lives, and for that you should feel happy.
