#unrelatedly cue hal and clark getting into an argument about mach survivability

[burins]

i've seen a number of fics write clark as not knowing or understanding human limits and making either stupid or sexy mistakes about it... but honestly i think clark, who has spent about 20 years studying human limits very, very carefully so that he doesn't get nabbed by the government/outed as a hero, would have a better understanding than most people of what, exactly, the human body is capable of!
