In which case then we are in perfect accord.I wasn't particularly talking about injuries that reduce a character into negative hit points, which have their own complexities (in 1st ed AD&D, a week's recovery after binding, and in 3E the need for binding - though, frankly, binding wounds in 6 seconds or so isn't redolent of anything very serious).
I was thinking more of, say, a 2nd level PC who drops from 15 hp to 1 hp in two blows from an orc in a combat. Thos 14 hp will heal in 4 days (at 4 hp per day), or in 2 days (at 8 hp per day) with nursing care (which nearly any trained nurse will be able to provide by taking 10). Therefore they cannot, in my view represent anything very serious.
A character at 1hp is still acting at full capacity and so is not troubled by their "injuries" or perhaps more precisely their current condition based purely on hit points. Complicating this (from trying to work out what is going on) is that tougher characters can most likely take quite a bit of roughing up yet still be at combat capacity where as a non-combat wizard takes a thump to the stomach and they're more than likely incapacitated. JeffH raises an interesting point in regards to poison saves, with a poisoning hit representing some form of physical contact and injury. But realistically, the damage caused is purely relative to the time taken to heal from it and so an injury that can be naturally healed in a day (4e/5e) or a handful of days (3e) is never going to be that serious, and certainly not to the violence level of guts across the floor.
