It is a play on the observed phenomenon that many who are either vegan or into CrossFit bring it up all the time, even when it does not directly relate to the situation at hand. For example, my post above. The style of my workout routine doesn't add much to the context of long commutes.

Thanks. I thought there was a specific relation to people in medical emergencies ("heart attack", "might be dying"), but those words were just there for emphasis.
