> Although there was a negative correlation between county altitude and all-cause mortality (r = −0.31, p < 0.001), there was a strong positive correlation between altitude and suicide rate (r = 0.50, p < 0.001).
While working in a lab in the Netherlands in the late 2000s, Strous noticed that a type of methane-feeding bacteria often found in lake sediments and wastewater sludges had a strange way of life. Instead of taking in oxygen from its surroundings like other aerobes, the bacteria created its own oxygen by using enzymes to break down the soluble compounds called nitrites (which contain a chemical group made of nitrogen and two oxygen atoms). The bacteria used the self-generated oxygen to split methane for energy.

Does this mean no one was in the living room when he left it? Or does it mean no one was in the room he entered when he entered it? Or both?What is to stop a person from being in multiple rooms within a 15 minute period?
