It exists in the universe of Gattaca, that's why you see him exfoliating every morning in the shower To become less of a "good shedder" >Offices 2–4 were all known to be occupied by the same owners for many years (see Supporting Information 1). The owners were detected as the main contributor in background samples and in most instances sufficient DNA accumulated to identify these individuals after 4 weeks of occupation. In contrast, office 1 was occupied by the current owner for only 1 year, and this owner (a known poor to intermediate shedder) was not detected at either time frame. Notably, there was a prominent male profile (further discussed in Section 10) that was detected in most background samples, but not at any other time point after cleaning. It is possible that this male profile is from the previous owner of the office who had a much longer duration of occupation and perhaps was a better shedder
