It's an important question. We need to ask it to ourselves multiple times. In fact, sometimes our bodies just tell it to us. But I am definitely not collecting, I guess you could say I'm collecting some type of feelings from my stomach or how weak I feel or not. But it's definitely not data with variability. I'm either hungry or not hungry on a given day. I mean, if you said broader, how does my hunger change from day to day, and you came up with some type of a scale for rating your hunger, okay, maybe that's more statistical.
