I am sure you are right Sue. My brother gave his body to MD Anderson for research when there was nothing more to be done for him. There was no med for lukemeia for older adults that was successful like in kids so that was what was tested on my bro. He was 64 and it didn't work, a local weatherman, aged 42 was in the same test and was successful, he is still alive and in N Mex I believe.WE texted a lot about that while he was living and I was a bit surprised when Don took a turn.
