Excellent post Doc Alan...I echo what Terpe has said and greatly appreciate your input.
I remember you saying you had something to do with genetics in Edinburgh.
Thanks again Alan
Btw...you state the mutations will be balanced out by our modern living standards.....I remember when I had my first children in the early 80's...I'll tell you without shame we were dirt poor in those early years...no way could I afford then what we can give now and that includes throw away nappies!...my kids were always poorly....not the case now....infact the opposite....how lucky we are
