Hi, , Kevin Coupe here, and this is FaceTime with the Content Guy.

Y'know, more and more it seems like the stuff we used to count on no longer can be counted on.

I find this disconcerting.

For example … did you know that 98.6 degrees Fahrenheit no longer is the average normal human body temperature?

I find this disconcerting.

A story in the Wall Street Journal explained that "body temperature is a crude proxy for metabolic rate, and if it has fallen, it could offer a clue about other physiological changes that have occurred over time."

The thing is, we all know that people are taller, fatter and live longer than they used to, and scientists say that this drop in average normal human body temperature is related to all these things … though the story also points out that they're not sure which one is the cause and which one is the result.

I find this disconcerting.

The thing is. 98.6 has been held as the standard for normal average body temperature for more than 150 years. And now, suddenly, studies are suggesting that it is 97.5 degrees.

Of course, there could be other factors at work. Like how people's temperatures are taken. There used to be two ways - orally and rectally. (It wasn't that long ago that doctors - and I'm thinking here of our family pediatrician when I was a little kid - believed that rectally was the only way to go.

Even as a little kid, I found that disconcerting.

Now, though, there are all sorts of ways to take a person's temperature. You can stick the thermometer in people's ears, or run it across their foreheads. So maybe that has something to do with the change in numbers.

What I also find interesting is that not everybody has gotten the message.

MNB readers know that earlier this week I got as colonoscopy. As they were getting me ready, they took my temperature, and it was 98.2. And so I mentioned the fact that the numbers have changed, and the nurse gave me a strange look and said, "I hadn't heard that."

I find that disconcerting.

You can't count on anything anymore. Not in how you take people's temperatures, nor how you view and cater to customers' desires and needs.

Disconcerting, right?

That's what is on my mind this morning. As always, I want to hear what is on your mind.
