In the medicalized health world we live in, most people assign higher importance to objective numbers than to subjective experience and functionality
It’s not that hard to assess your metabolism, physiologic capacity, and stress tolerance by observing yourself and your habits.
Remember, the goal is not to have perfect bloodwork.
The goal is to become as highly functional and anti-fragile as you can across the widest range of contexts.

I highly recommend this article to expand your understanding of what it truly means to be healthy, beyond bloodwork.
