I have heard that they (whoever they are) are considering lowering what is considered 'normal' body temperature because so many people have below-normal body temperature nowadays.

As long as I can remember I have had below-normal body temperature. Mine is usually one degree below normal. When I register 98.6, then I am running a low-grade fever.

In all my studies I have learned that people who are burdened with mercury in their bodies most likely will experience below-normal body temperature. I had hoped that once I had the source of mercury (amalgams) removed from my body that my body temperature would improve. Sorry to say - that hasn't happened. Normal body temperature for me is around 97.5 degrees.
