wolf63, what makes you think I'm "normal"? Here's my agenda my friend: if I can do just a little to explain scientific concepts to the layman and those less educated than myself, then I'm a happy man.
There are many things in this world that baffle me and I'm certainly not a genius but I don't feel there's anything wrong in conveying and returning some of the knowledge I've acquired over the years at the expense of the taxpayer back to the general public. This is the very reason why I take time out to teach classes in years 7 to 11 at two of my local comprehensive schools. Believe me, it keeps my feet firmly on the ground - I was educated in a Secondary Modern School and then a Grammar School after picking up enough CSE's.
In essence, intelligence and learning in others has meant little to me and I treat everyone equally even if I have to adapt the concepts under discussion.
Right now, I'm checking some complex research work on Glycosyltransferases written by a student. I find reading and writing on AB relaxing and can do it alongside most other things in my offices at home and work. I, like many others on here, appreciate the camaraderie on AB and it is worth its weight in gold.
Perhaps now you can see why I can spend time with you on AB.
