What it specifically helps me to understand are things like: probable outcomes, symptoms in greater detail, as well as how they manifest in patient populations, explains it as if I was a 10/15/20 year old in detail to help me understand the basics of what might be going on, similar things in possible pharma options, general response treatments and pros/cons, etc.
I'm not using this to perform self-surgery or build a belief system :), I'm just trying to learn and understand what is going on at a better level.
Hope that helps :)
