DEAR DOCTOR K: Even when I'm feeling fine, my body temperature is rarely 98.6 degrees. I thought that was the normal temperature. Should I be concerned?
DEAR READER: It's still taught to schoolchildren: Normal human body temperature is 98.6 degrees Fahrenheit. But people are different from one another. That's as true of their body temperature as it is of their height, the size of their ears or the color of their hair.
