I find it amazing that we give so much agency to doctors over our health while we know relatively very little about our own bodies and health.
And biology is a big part of that learning.
I now study medical books on my soare time.
Would recommend “Clinical Methods” as your first foray. You will understand your doctor and the biology is immediately applicable in your Daily life. Ie how to deal with fevers in your kids.
After that learn about your skeletal system and biomechanics.
Next Neuro degenerative disease and the brain.
Once you’ve caught the learning bug, you can go into 1st year Med School curricula and then the rest from there.
Some big parts of medicine is relatively useless - psychology for example.
Would recommend learning meditation ina real way and reading “Right Concentration.”. Learning about jhanas and mental states.
I remember as a kid when they asked me what I wanted to do, I never understood why I couldn’t do all of the above.
