You can have all the money in the world, but if you don't have your health, you're broke.
I came from an unhealthy background (overweight, family history of heart disease and diabetes) and over the past decade have reduced my "health system" to a few critical things that works incredibly well for me:
Everyday: Exercise/mobility, eat as well as I can
Every 2 years: Full body MRI
Every 5 years: Contrast CT of my heart
We documented my protocol and followed me around for a week while I ran it.
