The findings illuminate both the nature and the limits of the human predisposition to measurement
Only makes sense, the need to judge distance, count, and measure are crucial to survival,
"How far must I throw spear to hit big furry beast?"
"Ugg had three fat women, now only count two...where third fat woman go?"
"Ugg kill Grogg for stealing fat woman, take three days to make shape spear, Ugg kill Grogg in four days"
"Grogg fat like woman too, must make sharp spear three arms and five hands long and thick like big furry beast penis!"
...how thick IS big furry beast penis?"
