short-lived

The cool thing about portraying time travel, whether it be in books, movies, or television, is that no one has figured out how to do it in real life so you can pretty much just make it up as you go along. It's not as if there are people at home who have actually time traveled yelling at the screen: "Damn it! That's not how we did it when we went back in time and used Marie Antoinette's head as a soccer ball!" That is, however, a line from my new screenplay about time travelers who go back in time for the sole purpose of kicking around severed heads. It's called The People Who Go Back in Time and Kick Severed Heads Around.
