> Aside from life support in one's final days, most practical medical interventions for prolonging life also result in significant improvements in quality of life.

I can assure you that you'd never ever hold that opinion if you were a healthcare worker. A big part of our job is to maintain alive people with a horrible quality of life who should be long dead, oftentimes without even being able to know if they'd in fact prefer dying...

There is a lot of subjectivity in your conclusion.

Healthy diet for example is not a singularly defined term and depending on specifics can be argued to lower quality of life even if they improve health.

Are you over 50? A year over 50 feels as satisfying as one month being 18. I’d rather enjoy what I have left.

Can you paraphrase this? Having trouble understanding what you mean and I want to know.

I'm not afpx, but I understood them to be saying "you have fewer good days when you're 50 than when you're 18." That is, health wise, it's better to be 18 than to be 50. :)

A related concept is the quality-adjusted life year (QALY), which is used when weighing the cost/benefits of certain interventions.

Oh so when you’re 18 you extract as much pleasure/utility/etc from a month of life as you do from a year at 50? Maybe my late teens were lame because those times were not that awesome lol. Nor any other time I can think of. It’s all mostly been the same, except, say, when I was 4-8, when time just dragged on and on so slowly everything felt like eternity all the time. Then that ended and everything has been more or less the same from a psycho-emotional perspective.

Health-wise yeah it’s great to be young :)

How does one start to see a healthy diet as a “quality of life”? QoL is when you eat a chunk of anything you feel like, down it with soda and feel nothing bad next hour or day. I could do that, lie on a couch watching mtv or go fall from a tree when I was young. That was quality of life. Everything after 30 is just a life support. You improve life support by a diet or a (careful) walk.
