I was going to comment on this but the wife said to take the clothes out of the washer and put them in the drier.
Then she said to start another load and don’t forget the oxy clean.
So, evolution makes me think the pig smell worse than it did before, and it is immoral to wash your clothes. Flying from London to Glasgow… 
“This study is part of a larger body of research understanding how we wash and what drives washing behavior, according to the authors.”
I wonder how many millions that study is costing us!
