Understanding why health requires context, not just measurements There is something very appealing about a number. A number appears precise. It seems objective. It can be measured, recorded, compared, and tracked over time. Blood pressure has numbers. Blood tests have numbers. Weight is a number. Cholesterol is a number. Blood glucose is a number. Heart rate is a number. Even the amount of sleep we get is increasingly presented as a collection of numbers. Numbers are useful.

In fact, asking questions is one of the most important things you can do when trying to understand your health. But there is a difference between simply asking questions and asking better questions. A better question does not necessarily produce a simple answer. Sometimes it does the opposite. It may reveal that there are several possibilities, that more information is needed, or that the issue should be discussed with an appropriate healthcare professional. That is not a problem.
