I've separated my shoulder and my collarbone; I've messed up my knee a million times. I've broken my foot in several places. I've broken my toe a bunch, broken my nose a couple of times, and had a bunch of other annoying little injuries, like turf toe and arthritis and tendonitis. It's part of the game.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
