Garmin Body Battery proves when I'm sick

I’m always surprised how good some features of my Garmin watch work. For example the body battery: when I’m feeling sick the body battery is proving it.

It’s especially interesting that the pathway of the chart is almost the same if I’m sick (like fever or headache) or if I’m drunk. It proves - obviously - that drinking alcohol is not healthy, and it sometimes helps when the data is telling it straight to your face.

P.S.: today was one of the days when my fitness-watch showed me that I’m not “charged” and it’s also the reason I had to publish a post late again.
