No thanks Brian, perhaps later. At present I'm trying to write up some
papers on neurodegeneration. You may have gathered this current
preoccupation by the nature of my posts. It is proving extremely difficult,
I'm happy to make it a part time hobby and leave the real work to the bods.
As a layman the challenge in creating a good conceptual structures in order
to deal with the relevant research has proved hard enough, the last thing my
attentionally challenged brain needs is something else to think about!
Why won't someone prescribe me Dexedrine? Or for a challenge L deprenyl ...
