Intellectual quiz.

Well, the fact that biochemical processes are responsible for feelings, mental state, etc., is undeniable. By the way, here are two riddles (questions like these should be punished with death in trivia games, in my opinion ^^): 1. Vasily goes to work in the morning by elevator, from the seventeenth floor to the first. When he returns from work, he walks up the stairs to the seventeenth floor. Why does he do that? 2. Let's take the same Vasily, although these questions have nothing in common: Vasily came home from work and was about to go to bed. Looking at the clock, he realized that someone was in the apartment. Anticipating your questions: the clock is face-down, without an alarm, guess the other details yourself.
