You were medivac'd? That is cool! :D

I could see doctors, chase cures, see therapist, but in the I may be a tiny bit healthier, would I have anything to live on after paying off medical debt?

Exactly. I am not saying "don't be healthy" but do consider the value of chasing health.

What is 5 to 10 or 20 years more worth? How much healthier would I be?

It doesn't sound like a pleasant life to live long, but do little.
