I'm just getting back in the swing of things and just read through Bill Amick's delightful post. I think if anyone has not read it - they should. I think that is an honest and straight forward an answer as you can get on this site.
I don't think anyone can get too old - but I do think they can become too set in their ways. I think that most of the praise for youth comes through their ability to adapt to technology to become more efficienct. The praise for age come from making better decisions through experience.
Interesting discussion Paul - thanks
