70% of household dust is made up of waste cells and hair. While this might come as a shock to some, researchers have established that, over the course of a lifetime, the average pair of lungs breathes in the equivalent of an entire human!
Those who spend more time in recycled air environments with a large number of mobile personages, like office buildings, aeroplanes and hospitals, have been found to have a higher count of particles in their lungs tissues, coupled with an elevated macrophage count.
Michelle Green, Senior Technician of Higher Research in Louisiana, says, “We noticed a spike in macrophages, an order of one hundred times greater, between population samples when looking at lung tissue. Simon (A fellow technician) noticed the potential correlation and we performed further analysis to find out just what they were feasting on.”
The amount of ‘foreign human matter’ found was ‘interesting’ but not ‘alarming’, she said.
“It’s not cannibalism, if that’s what you’re worried about. Sure, an amount of digested matter is absorbed into the bloodstream, but it’s not like you’re chewing off a finger. What’s more, there’s a good chance that, among the billions of particles that have entered your system, you have most likely inhaled several celebrities!”
