Back in a prior life, when I was young at college...
One of my fraternity brothers, who was on the college yacht team, asked if i wanted to go sailing.
I said yes.
As I've noted here previously, my college was in New Jersey, right on the Hudson River, across from 34th Street in Manhattan. So going sailing on the waters of the Hudson River was good stuff.
I went out on the river. Had a great time. Got my feet wet, so to speak, and literally.
A couple days afterwards, I noticed that the trim pieces of my sneakers were detaching from the sneakers.
Long story short, the chemicals in the Hudson River, where we sailed, had reduced the adhesive qualities of the glues that were holding my sneakers together.
Fortunately, only the trim pieces were affected,
Such was life in the 70's when corporate pollution ruled the Country.
If you're curious, pop into your search engine of choice, "GE PCB hudson river" and see what you get... Here's a sample result...
...Between 1947 and 1977, General Electric dumped an estimated 1.3 million pounds of polychlorinated biphenyls into the Hudson River....
Were those PCBs the reason why the glue of my sneakers dissolved?
I do not know.
fwiw, that fraternity brother who took me sailing went on to become a Navy jet pilot. He was an awesome person.
