Ask HN: Do you track personal health data?

Do you track your health/fitness/wellbeing information in an organised way and review for insight? What do you track and what have been your findings?

I recently created a Google form with 30 questions which I complete each day. The idea is to track my health, fitness, and wellbeing to draw some analysis and conclusions that lead to better health outcomes (physical & mental).

I'm curious to know if anyone is doing the same and if I can learn from your experience.
