I wasn't aware of Dr. Scott Connelly or his Body Rx book and website. From the comments section of Tom's blog I understand that Dr. Connelly has been ill recently and his condition is seen in these videos. No matter, the information is solid and his presentation is good. I've got a slight problem with some of his language, but it's relatively mild.
