There are two similar but importantly different concepts that seem to be getting mixed up quite a bit lately. “Common” and “normal” are often used interchangeably now but this is a misleading and potentially dangerous practice, particularly when it comes to health. Common is not always normal and I think our morphing of these terms is becoming problematic. This is growing increasingly evident in the recent (and disturbing) practice of seeing what is common for Americans and thinking that it is normal for humans in general.
