We spend an extraordinary amount of time in buildings that are extremely controlled environments, like this building here -- environments that have mechanical ventilation systems that include filtering, heating and air conditioning.
Provodimo nevjerojatne količine vremena u zgradama koje su ekstremno kontrolirana okruženja, poput ove zgrade ovdje -- okruženja koja imaju mehaničke sustave ventilacije koji uključuju filtriranje, grijanje i klimu.
