So I came across a YouTube video awhile back where there were wondering medics that would come along and heal you if you were beaten up, unconscious, and bleeding out, etc. Is this available somewhere on the GoG version? Thx.

Not familiar with that mod but what you can't find on Nexus you might find at Skymods.

Also might be worth noting that the higher your toughness the slower your wound degeneration. At least that is one thing you can do to make those situations more manageable.

I usually keep a very tough enemy as prisoner, equip them with a very weak weapon and spar with them. It works best if you wear the best armor possible otherwise you will get knocked out in one or two hits. Sustaining bigger hits has a bigger incremental impact, but its counter-productive as you spend too much time knocked out. Taking chip damage is better as it has potential to spread between many body parts over a long duration resulting in more sustained training sessions.
