Could someone please explain the main difference(s) between Gout and Arthritis. My late father had Gout, which mainly affected his knees, and was always getting grouchy when people claimed he was arthritic, saying it was totally different.

Also, as his 27 year old son, I am concerned that I am going to get it, or already have gout. Bearing in mind that my father never drank port, or any of the other cliches, any suggestions as to how I could put it off as long as possible?
