Healing is an important ingredient in any roleplaying adventure. From the clerics of the original Dungeons & Dragons to advanced sickbay facilities in futuristic space games, you need to have some way of reducing the amount of damage an adventurer has sustained and getting them back on their feet again. In setting where technology is not up to the task, magic often steps in. This is why the deadliest games you can play are pre-industrial historic settings without fantasy elements.

And why if you're player and your GM suggests a pre-industrial historic setting for a game, you need to insist on having access to magic.

{Back at the base, Luke is in a giant tube filled with a healing fluid}
Han: Hey, kid. Hear you're doing great. Boy, I bet you're reeeal thirsty in there. What say you and I head to a bar later?
2-1B: {a surgical droid} He can't speak. He's in a bad way.
Han: I hear there's this one called the Dagger Bar. Great place.
2-1B: He can't even hear you. He's in... an induced coma.
2-1B: It's a miracle someone from a desert planet survived in the snow that long.
Han: The drinks are really rich there, if you know what I mean. Heh heh.
2-1B: Please stop knocking on the glass, sir.
Leia: Han, you saved Luke. That took a lot of guts.
Han: I know, right?
Leia: I don't know what I'd do if he died. I feel this... deep connection with him.
Han: Me too, Princess. Me too.
2-1B: Are you two begging for an ironic death at this point?!
