Hi Lowell,

Gosh! Well surprises never cease. I see by the list of posts, it got interesting while I was laying my new brick walkway out back.

I can honestly say there is no one else in the scientific community who has been so gracious in teaching me so much. You have unlimited patience. So how does one thank the teacher? Well, the best way is to use what you learned and keep adding to it until you have a firm foundation of knowledge to draw upon. I've gotta ways to go on that yet.

I hope you'll come and visit often. Its always nice to have a doctor in the house.
