Hong Kong has one of the highest life expectancy of the world and a major contributing factor is high population density. Paramedics are able (and must) arrive within 12 minutes of an emergency call, which is probably the most important time to keep people alive. Doesn't mean Hong Kong is a decent place to live though.

Have you got a source for that?

But your point is valid, life expectancy is not the same as quality of life.

I'd personally rather live five years less and be in great general health than be slogging through pain and medical bingo for my last 10 years.

Where is the source that says one is caused by the other

My opinion. Basic logical deduction anyway. Are we not allowed to express personal thoughts without quoting someone now?

It's probably a very complex thing and both sides of the discussion can pick something to attribute for. For example, you can say that it's because of the opioid crisis in the USA and pretend that it's happening in isolation - just some bad actors doing bad things that don't have anything to do with anything else.

Young people dying of drug overdose.

Good point, that's contributed 100k deaths per year recently. Also Covid in the same manner for ~ 1 million will skew the average age down.
