Sure, but 'F' is a lot shorter than "whichever unit doesn't kill the dinosaur."
Weird, my browser somehow doesn’t render the title as “T. Rex Had a Body Temperature of 97 Degrees whichever unit doesn’t kill the dinosaur”. It just leaves that last part out, making it even shorter than “F”.
"T. rex was warm" is even shorter again. I think we’ve established that omitting information saves space.
My boyfriend and I were confused because I thought humans have a body temp higher than 97dF and somehow the title made me think this was exceedingly high.
