You are going to like this one, Clint was in a plane crash back in 1951. In his Biography he writes about when he got into a Douglas AD-1 Military craft (Navy bomber) and the events that took place soon after. This is what the man himself said in his book;
"And then it started getting dark, and I lost him. I didn’t know whether he was alive or where the hell he was. And I wasn’t about to start yelling, because it wastes a lot of energy. I went through jellyfish schools and all kinds of things, and they became fluorescent at night. It was like some science-fiction deal. By this time, you know, your mind is–talking about hallucinating…" "I kind of worked my way into that–just partly luck, because everywhere the water was very rough. And I got into this spot and had a really rough time climbing out."
The plan went down due to technical malfunctions where he and the pilot (2 person plane) both plummeted into the water. After swimming for hours Clint found the shoreline due to the luminosity the kelp provided. Once on shore Clint linked up with the pilot who too survived. I like to imagine them both sparking up a fat cigar at that point and having a laugh.
Scientifically backed way to kick the bad habits and build the good ones!
