Hi Alan, well, you gotta do what you gotta do and make the best 
of things.  I'm aware of your situation and feel, like everyone, 
helpless when I hear about folks dealing with cancer.  I just 
keep in my mind the total relativity of things knowing that I 
will be passing along the same road as you, soon enough for 
whatever reason.  It's just tough to know that there are 
limitations that we can't control that we encounter on the path 
of life.  I truly wonder about Ray Kurzweil's point of 
singularity if I have the name right.  Will we ever be able to 
record our consciousness so we can live on in machine form or 
something? Far be it from me to say it will never happen, but 
it's certainly difficult to imagine, unless you are Ray Kurzweil 
that is.  Best 73, Jim WA6EKS
