buffdoc,
Now that response is the reason I am a member on this board. To learn from people with more experience than myself in the subject manner. I honestly had no idea that the size difference between an 18 and a 22 gauge was that much more harmful. More painful I know!
I listen and value your experties and experience. I'm not an M.D., but rather a computer engineer, and a Professor of computer science. If you, or anyone else on this board needs any help in that department, I hope I can give back a little.
