While you are technically right and this does apply in many countries, it's not as simple as them being arrested for trying to kill themself (in most countries). If you arrest a suicidal person, it's probably going to just make their mental condition worse. Instead you are more likely to be sectioned, forcing you to have to spend time in a mental health institution. However, assisted suicide and suicide pacts are illegal almost everywhere, and if for example one party in the pact survives, they may be tried for manslaughter.

Only hours? Mine takes up multiple days.

? It's more dense if that's what you mean... unless there's a joke I'm missing out on here.

Are you having jade va du? (It sounded good in my head)

It's to do with increasing the time it takes for the car to come to a stop. It is proven by basic physics, for example Force = Mass * Acceleration. So if you have a car like an old Volvo, a solid brick, it may take you 0.2 seconds to come to a stop. Compare this to newer cars, which use crumple zones a lot and it may take you 0.8 to stop when you crash. This decreases the total force by 75%. As a result, people tend to be safer, even if you may have to replace the bumper or even whole car after relatively small crashes. For older cars, most people tend to think that just because the car's intact and didn't crush your legs, it's safer. In reality, internal bleeding is much more of an issue in cars built like bricks, so the 75% force reduction which I used as an example means your internal organs are moved around much less, making internal bleeding more unlikely and less severe.

By volume, yes.

Lots of Chinese people have western names when talking to western people, it's much easier for us to say it as Latin languages are nothing like Chinese.

I can be worse.
