I've been thinking lately about what is meant by the term"normal."
It first occurred to me when I was looking at a set of lab results from a blood test. For every thing tested there was a "normal range." Noticing that a few of my readings were outside of that range I queried my doctor about whether I should be concerned. "Oh no," he replied, "We don't worry until the number reaches X." In this case X was a number waaay higher than the top of the normal range. So, normal is all relative. There is "normal" and there is "higher than normal" and there is "concerningly higher than normal."
