Finding a 100th problem is a problem itself, but resolves itself immediately... So you only have 100 problems when you have 99 problems and looking for another. Trying to resolve this paradox is a problem itself and I think it balances to a steady 100.
They already can by putting your finger on the camera and lighting up your finger with the led light. Then it detects the rhythmic changes picked up by the camera... At least 10+ years ago. It was a good novelty feature, but turns out, for most healthy people, checking your heart rate gets old after a few runs.
Assuming a conservative 0.5 gallons per hour at idle. A gallon of unleaded gasoline has ~153,000 watt hours of energy. At 20% extraction efficiency, that's 30,600 wh. That's 15,300 watts being burned to charge a phone. A typical phone charger uses 5-20 watts.
Human anteaters live among us and they look just like any other human.
If you eat one ant, you are an anteater. You may not even have consciously have eaten one. It could have been hidden in your sandwich or mixed in with a soup. You may be an anteater and not even known it 😳
Living in the US, back when I was on a high deductible insurance plan, I would avoid doctor visits because it would cost over $100 for any single check-up. My employer put enough money in a health savings account to make up for the high costs, but I had the mentality of "If I didn't see the doctor, I could bank the $100 for a later emergency." I'm the type of video game player that will stockpile health potions, never use them, and then die cause I didn't want to use them. I realized this is a fucked up situation and so I switched to a more expensive low-deductable plan and will now visit the doctor when "I think I might need to" instead of when "I really need to."
But yeah, lots and lots of people on low-premium (low monthly payments) high deductible plans with that save money mentality. They only see the doctor when it gets severe.
