If you're allowing a single data point to have that much power over what or how you think, you've already lost. Especially if you decide to ignore context like "I just lost water by running and I haven't had anything to drink yet", or even important variables like time of day. The number by itself is meaningless. Data (as in a ton of data points) with context can be incredibly useful. Don't blame the tool if you don't learn how to use it properly.
