It's easy to take something like "knowing where anything is" for granted, but somebody had to go out into the world and take note of all those  natural and cat-made borders. In the case of Japan, it fell to Ino Tadataka to create the first "complete" map of the nation.
I've trained for a long time to always 
take strides of the same length.
Entrené mucho para dar pasos
siempre de la misma longitud.
Treinei para andar com
as mesmas passadas.
