When I think about the liver, I’m often reminded of a comedy sketch from a Monty Python movie.

Most non-medical people don't know the difference between an artery and a vein, and the confusion is quite understandable. The truth is, arteries and veins connect to each other and are part of a circuit that transports blood from the heart to the rest of the body (arteries) and back to the heart again (veins).…...

In my last health tip I described how blood is circulated around the body. I mentioned that poor circulation can cause leg swelling, and promised to provide a fuller review of this very common problem.

One other important "sun safety" issue…...

Clostridium difficile (known as 'C. Diff' for short) is a species of bacterium that can cause severe diarrhea requiring hospitalization. This bacterium normally lives in soil, water, deli meat, and human feces and we are exposed to it on a fairly regular basis. It may not cause symptoms until our normal intestinal bacterial colonies are…...
