Comments always welcome.
It turns out that aging, though it has some negative correlates is a lot better than the only other available alternative. As soon as I agreed to come to work on this study, I looked at the grant proposal and noticed that there was also money set aside for a full-time programmer. That was in the days when I didn't understand how bureaucracies worked. But, never mind. Another programmer had begun writing special subroutines to run the experiments but took off before he got a chance to test or debug the programs.
