We all know sitting at our desks all day is slowly killing us, but we generally assume that the air inside our offices, at least, is pretty clean.

To test this out, the researchers over at Molekule took a volatile organic compound (VOC) monitor to both a modern office cubicle and an old jail cell at Alcatraz Federal Penitentiary. A lot of VOCs are harmless, but some have been shown to be damaging to human health, which is why air-ventilation is so important.

Don't worry, this isn't a definitive study on the air quality of workspaces - there are no control groups and no analysis of what type of VOCs are present in each space. But it definitely makes you think a little more about what you're breathing in at work.
