I am a retired neuroscientist. The science here is reasonable albeit simplified, and that works. I watched with skepticism and was initially appalled at the investigator's desire to retest until the data was more suitable. That would be nonsense. But the mea culpa resolved that. This indicates the direction was perfect. I was supposed to be upset (tension), and the tension was resolved with humility and self awareness. Brilliant. Each of the four romances were real, both sides were treated fairly. If I were nitpicking I would say the athlete owes more apology but that is the point really. We live with flawed people. We are flawed. Best line: " Jet lag is a social construct". Hilarious.
