"Recent discoveries are furnishing other important clues to the mystery of how the nerves' messages are telegraphed. Actually the nerves 'get hot' while carrying a message said Prof. A.V. Hill, of London University, England. It has even been possible to measure accurately the amount of heat they give off." - Popular Science (Nov. 1929)

The amount of heat my nerves give off is extreme. I virtually burned my hands one day when they were cold and I touched my leg. I could never understand where the heat was coming from because my core temperature is usually low at 96.8F.
