Dust, dust, dust
Here’s a little tidbit from one of Bill Bryson’s books, In a Sunburned Country:
“According to an article in the science section of the New York Times, every hour the average person ‘sloughs off’ 60,000 skin fragments, 160 million motes of dust, and 20,000 particles of clothing lint, among rather a lot else.”
For most people in first-world countries, all of that dust has detergents along for the ride.
It really does make a big difference for EVERYONE in the household to make the switch, and this is why.
