Clearly they meant the arithmetic mean of the weights of every outfit worn by anyone in the medieval period/area for protection in combat, weighted according to completion, time spent wearing them, and proximity to the geographical centre of Europe. It's not that hard.
My belated opinion is that it's a trick question, the correct answer is "like 20 pounds", or whatever normal leather armor weighs, since most people weren't knights. Not sure how common even hardened leather was in these conscripted armies. And then there's chainmail...
Dunno why, but I just suddenly wondered what life might be like if whenever a person got too embarassed, they violently exploded. This thought came totally unbidden and I spent way too much time considering each embarassing moment in my life, and whether I would have exploded at that point in this alternate timeline.
Have you seen or played Off?
TieTuesday did a LP of it. It starts slow, but it's pretty weird I guess.
EDIT: I hate leg sunburn (almost as much as hand or face). The WTF is that it hurts the most when I try to stand still. Sitting or lying down is fine, but some sort of compression happens when I stand in place, and it's... pretty unpleasant. Keeping it on the down low, though, since (also WTF, I guess, whatever) I'm having a pretty nice time visiting my dad at the beach.
I mean I really do want to be deep underground or back home on a cloudy mountain range, somewhere cool and dry and dark where I don't have to bite my lip to stand up. But this is pretty good. Cooking with him is fun. I showed him One Punch Man and Metroid Prime 2 and he's been explaining middle eastern politics and reruns of Babylon 5.
