Amazon is delivering a device that tests various blood cholesterol levels. That seems like relevant information. I have a blood pressure device, blood oxygen and ekg. Seems like they make something to measure blood sugar too...I don't know if that's a thing.  I asked Grok and it said I'm healthy    "Overall, these numbers paint a picture of someone in robust health—better than most peers. Of course, full health includes other factors (like cholesterol, blood sugar, diet, exercise, family history, and regular check-ups), but based on what you've shared, you're doing exceptionally well."  Blood sugar. What do dat mean?
