While I’m sitting on the exam table with my legs dangling, the neurologist reaches for a metal object. He’s already poked me several times with the safety pin so I’m wondering what he plans to do with this larger pointy thing. He grasps my foot and scraps the object on the bottom of my foot along the outermost side and under the toes. My big toe jumps and the other toes look like they are trying to get away from the torture device. I have just demonstrated a positive Babinski sign.

“When the doctor scraps the bottom of my feet, what is he looking for?”
A reader recently asked if high cholesterol can directly affect your sex life. The answer to this question is yes, but the effect may not be immediate. Studies have shown that some of the traditional risk factors for heart disease , such as high cholesterol, are also significant risk factors for male erectile dysfunction . An intact arterial blood supply is required for normal male erection, and it is thought that high cholesterol can impair normal artery blood flow. There are two ways that this might happen. Just like one can develop a blockage in the heart arteries, blockages from atherosclerosis can develop in the arteries responsible for erection. This could then diminish blood flow.
High cholesterol also can adversely affect arteries without developing blockages. Arteries not only need to be open, but they also must be able to respond to local hormones that regulate blood flow. One important artery relaxing hormone is nitric ox...
