Thanks Mark (BCSnob) for the scientific information. It is always nice to have your professional experience in science and research to help clarify certain topics.
As for me.... I've always had rescues, some mixed breeds and some "pure bred" dogs. Some have been healthy with amazing longevity and others, not so much. I just do the best I can to fall in love with the healthy ones... but that is tricky business since some of my favorite dogs have gone way too soon. Random and unbiased are my results, in more ways than one. :W
