Hi Tool,
Glad to see you here again. I was not here when you left, but I've been here since mid December.
Now you can do some of the "heavy lifting" answering a lot of the biophysiology questions, the answers to which do not always come quickly to my mind. I have to dig out the medical books, and I am known to hit the medical research journals so I will be accurate.
I look forward to more of your posts!
