How much time spent healing? Varies from game to game.
I remember one game had players wander out of a town, get lost in the woods, and then spend three weeks healing after getting zapped by a standing stone. Only the ranger was active, the rest of the party was comatose for three weeks. They make it into town, get into a bar fight, then spend two weeks recovering. The only healing came from an astrologer named Fred. Fred had first aid, and a couple of minor healing lists.
My current group generally has some sort of healing: lay healer or channeling healer for the most part. If possible, I try to have some sort of independent healing for my character. As a result, my group tends to heal as quickly as the healer can regain power points...
