It is a crude, crude, crude measurement that gives us a broad stroke indication on how healthy someone might be, but it doesn't go into the detail.

And the detail is what matters here.

And what Andrea is doing there is far more important.

So please stop the fixation on the BMI.

Focus on what you're already doing because you're doing everything perfectly.

It's just a really broad, free, easy tool for us to use.

But what would be better is body percentage fat.

And what would be better would be something like VO2 max, which is how well your heart delivers food and oxygen to your organs.

But those are really expensive things to calculate.

And so we've still stuck with this free, broad thing.

It's not backwards.

It's not backwards.

But it's useful on a broad population scale.

But an individual scale, I wouldn't be using it.

See you next week.

And remember, no appointment necessary.

That causes over 99% of cervical cancer.

If you've got unexplained for three weeks or more, get that checked.

It could be frothy, it could be thin.

Like if it's new and unusual for you, we want to see you.
