me: 5'10" in meatspace
most doorframes: made to accomodate people of like 6'2"
the roof beams in my attic room: p. low, well below chest height tho.
this weird stone ledge that juts out from the ceiling because it's where the original house wall was before the extension was built that now has the kitchen/dining room in it: quite a bit shorter than that but still plenty of clearance.
my head: repeatedly banged against all of these things somehow despite my best efforts to not.
