... if you connect a blood pressure monitor, yes.

This app isn't figuring out your heart rate with just the phone's hardware. It is displaying heart rate data from Apple Fitness, which comes from heart rate sensor data (e.g. the one on an Apple Watch)


Most vehicles are mechanically capable of going that fast because thats how fast cars can go when they are given the amount of power that consumers want when accelerating to pass or merge.

Most vehicles do have software speed limiters, which are typically set to the safe mechanical limits of the vehicle when manufactured (often, the speed rating of the tires).

The reason software speed limiters are not set to the highway speed limits in the US is because:

1. They might be used in places other than on highways subject to US law

2. Laws change

3. Manufacturers are not required to


Many of the people killed by speeding are not, themselves, speeding.

Why 70? The maximum posted speed limit in the US is 85.

Driving on a race track is one. The vast majority of vehicles on race tracks are/were street vehicles.

It often isn't charged when a driver is sober.

Traffic law enforcement is a highly localized issue in the US. While there are places that will pull people over for going 5mph over and traffic is calm and orderly, there are also places where traffic laws are rarely enforced. In major cities it is not hard to find roads where severe traffic violations are routine (speeding 20mph+ over, driving on the shoulder, running red lights, etc).

Don't make the mistake of presuming that levying a legal penalty equates to perfect compliance. When faced with a choice between compliance and survival, people will choose the latter.

If policies continue to push more people to operate vehicles extralegally, problems caused by these drivers may get worse instead of better.


Uninsured/underinsured motorist insurance are literally line items on my car insurance bill.

Those were on my late wife's bill too.

After she got hit, ultimately leading to her death in time, by an uninsured guy we had to get a lawyer and fight Eire Insurance for three years for them to honor that line on the bill.


304 stainless is already strong enough that you could make a durable spoon thin enough that it would be painful to use. And it is cheap.

8–11% nickel, not antibacterial, and five times weaker than this CuLiTa alloy in the annealed state. Thin out the middle and leave thick edges to avoid pain. None of this is an option with this new alloy unless someone finds a cheaper way to make it and probably some kind of beryllium-copper-like precipitation hardening process so you can form it.

Nickel-free (e.g. 18/0) flatware is just fine from an engineering perspective, and it’s cheap, and it sticks to magnets, which is fun. It’s even available as fairly nice, decorative name-brand products.

And I found some studies suggesting that 304 and 316 stainless steel leach very little nickel when in contact with food. It’s the cheaper nickel-containing stainless steel that’s a problem.


> Thin out the middle and leave thick edges to avoid pain.

Ok but if you do that then what is the point of the exercise? I thought fancy flatware was thin because of the appearance. If the edges are thick doesn't that defeat the purpose?

The equivalent thickness being something like 5x stronger is of course the benefit here.

I don't think price is an issue for high end home use items. Rich people buy far weirder and more expensive things.
