I've never seen a corporate leadership team with so many people at a healthy body fat percentage and looking healthy in general. That's partially because this team skews so young, but still this is remarkable. Even a random sample of 22 people from the United States in their age demographic would be extremely unlikely to yield a result like this. Even Elon has now lost nearly all of his stress-eating weight from 2018-2019 and looks a lot better rested.
I don't mean to add to the social stigmatization of being fat and out of shape, and anyway shaming demonstrably doesn't tend to work well for convincing people to sustainably change the underlying behavior. I will also add that I am aware that some health conditions and disabilities are not readily apparent visually. However, as a retail investor I have some advantages over institutional investors and one of them is that I'm allowed to include information in my thesis that would normally get someone in trouble for saying it out loud in a corporate environment, and in general these things can be inferred pretty reliably on average with visual information.
The scientific studies are clear: Physical fitness, nutrition and body composition, all else being equal, profoundly influence energy, mood, drive and intellectual performance, all of which I think directly affect engineering innovation performance and team cohesion. Even animal studies on e.g. rats have shown this, so it's not just a human phenomenon. I don't know why Tesla's team has such an unusual lack of excess body fat and appears pretty well slept too, but this condition is surely helping their ability to sustain the intense, long workdays necessary to achieve the progress we witnessed yesterday.
