Tatiana V. Chernigovskaya. (№ 347414)

The brain remembers by which he passed, smelled, tasted, heard, touched and so on. The brain is not a sieve. Nothing poured out of it. We, roughly speaking, do not forget, just most of the data lies in the ""Other"". Therefore: do not listen to bad music, do not read bad books, don't shit there, don't need stuff to drink, no need to communicate with bad people.
