At least some of this will be stress. If you're enjoying something, then you won't be stressed. If you're feeling positive and delighting in what you do, then you won't be stressed in unhealthy ways. This looks similar to the Mozart Effect, which turned out to be that if you liked something, your brain functioned better.
Yes, charging around the stage playing rock music isn't exactly gentle, but it IS extremely good exercise for the heart and the rest of the body. Again, that's going to have positive effects.
(We can ignore Keith Richards in this model, as he's older than the universe and only created it as a place to store his guitars.)
Most posters seem to be assuming it's a scam. I can't possibly think of a reason why they might think that. (A few million, yes, but getting it down to one is hard.)
However, that's almost by the by. It's rated for 5G. 5G is old. 6G is the new standard and WiFi 6 has been around for a while now. If you're actually serious about designing a new phone from scratch, and have not yet released it, you'd almost certainly want it to be 6G-capable. Nobody in their right minds designs for yesterday's standards, when they're going to be competing with tomorrow's products.
This, to me, is far far more important than whether or not it is real. If you're designing a product for a market that's on its way out, you've got a serious problem. If you're clamouring for a product that's designed for a standard that could be phased out by the time you see it, then you're not thinking straight.
Why does this matter, if the product isn't real anyway? First, we don't know it's not real, we shouldn't assume that. But, second, it means that nobody thought it was worth bothering with taking the potential customers seriously. The customers are merely meat with cash. That's not an attitude I can respect. Whichever vendor is making these phones is worthy only of my utmost contempt.
The problem isn't the population. Bedrock can handle more than that. London isn't sinking because of all the people (and London is huge!), it's sinking because the ice sheet that pressed the Highlands deep into the crust has been gone for the last 10,000 years, resulting in the entire island tilting back to where it naturally should be. You could move London's population into the Great Glen and it would not make the slightest difference - London would still be sinking. The ice sheets were a whole lot heavier than a few tens of millions of people.
(Ok, it would make a difference. If the rich people actually lived in Scotland, the transit system and public services would see a thousand percent improvement inside a week. If they were also forced to speak Gaelic, English would vanish in a month.)
Aquifers can be deep. The aquifer that supplies the town of Buxton in England is so deep that it takes rainfall 5,000 years to rech it.
The rule on staying alive as a program manager is to give 'em a number or give 'em a date, but never give 'em both at once.
