Game shows are a great example of ordinary people, some of whom are very smart, making less than stellar decisions under intense pressure. I'm afraid I can't point and laugh too hard, because I resemble that remark; in flying, it's why I like my checklists so much.
In the gym, it manifests as a really hard time counting to five. Yes, five. Like the number of fingers on one hand, five. No, I can't move my fingers to track - they have to stay gripping the barbell, because my work set is, by design, the heaviest weight I can handle.
And when my entire focus is on completing this barbell movement, in perfect form, with the heaviest weight I can manage, straining the limits of my ability so I can force my body to adapt to an even heavier weight... it gets really hard to remember things like "Is that the third time I've accomplished it, or the fourth?"
This leads to technical errors, like sets of 6 where I'm so exhausted I flirt with injury as my form gets sloppy... because I was supposed to stop at 5, and lost count. (I default to more reps instead of fewer reps, in a "When in doubt, assume you have more work to do." Fitting right in there with assuming fuel burn is higher than estimated, there are no tailwinds ever, weather is worse than forecast, repairs will end up at double the cost and the time estimated, and there are never enough Eno's fruit salts to cover the whole crew*, it's a good way to make sure you don't get caught short. Some people call it pessimistic; they also tend to wonder why life is fond of hitting them out of the blue with unforeseen problems.)
I will feel really, really silly if I end up getting a coach again, just so she can stand there and count to five for me. Maybe I'll bribe my husband instead...
