So, imagine I have a plank about two feet wide and 30 feet long and I'm going to walk on it, and you see I can walk on it without looking, I can go back and forth and I can jump up and down.
Zamislite da imam dasku pola metra široku i 10 metara dugu spremam se hodati po njoj i vidite da hodam bez gledanja, i mogu ići naprijed i nazad i skakati gore i dolje.
