So what are you doing in 1E and 2E for the weeks that you're "healing" (game rules term) up to full HP? If you aren't healing from injury, what exactly is it you were doing?
In 3E, what are you doing when you're waiting for days while "healing" (again, game rules term) up to full HP? If you aren't healing an injury, what exactly's going on?
You hope to regain the favor of the gods? I really don't know, since it can't really be injuries, since if no further hit point damage is dealt, you can do all the crazy stunts you could do when you where fully healed.
Think about it - even after being reduced to 1 hit point, you can still run, make jumps, tumble, climb, stick your sword into enemies. But whatever these hit points thingies represent, it took you days (without magical help) to recover it. What are they?
If they were injuries, your abilities should be diminished when losing them (or lead to you losing even more of them, if you're performing strenuous activities). If they are not injuries, what does it take them this long to recover?
I don't know what hit points where in 3E, or earlier editions. I was happy to accept that there was no kind of injury penalty, despite this being not leading to something making really sense if you take the rules for "physic and biology of the game world". (At least if I'd want a game world that has some resemblance to real life.
Both in 3E and 4E the closed to reality you get is if you assume that adventurers can always avoid serious wounds (unless they die), and everything else are scratches, or "just a flesh wound", and they can ignore the pain or other limitations resulting from that. In 4E, these scratches or flesh wounds don't need to be tracked any longer over the period of extended rest. They might still exist inside the game-world, but they are outside the model of the game world.
