This is good news. The worldwide trend for more than a century is that the countries that are now developed countries have been gaining about 2.5 years of life expectancy each decade (sometimes expressed as "six hours each day").[0] Girls born since 2000 in the developed world are more likely than not to reach the age of 100, with boys likely to enjoy lifespans almost as long. The article "The Biodemography of Human Ageing"[1] by James Vaupel, originally published in the journal Nature in 2010, is a good current reference on the subject. Vaupel is one of the leading scholars on the demography of aging and how to adjust for time trends in life expectancy. An article in a series on Slate, "Why Are You Not Dead Yet? Life expectancy doubled in past 150 years. Here’s why,"[2] gives background on the incremental changes that have increased life expectancy. ("Period life expectancy" is what is usually reported for a whole country. But cohort life expectancy provides a better estimate of future lifespans of young people today,[3] and is still steadily on the rise around the world.) Life expectancy at age 40, at age 60, and at even higher ages is still rising throughout the developed countries of the world.[4] It's great to hear that India is enjoying this kind of development too.

Are longer lifespans better by definition? I realize fully I'm in the minority on this, and y'all can feel free to live forever, for all I care, but I wish that my personal life expectancy was about 40 years shorter than it is. That would have felt about right to me. Complete, and without too much decline. I mean, is everybody's desired lifespan just "as long as possible?"

  This might be one of those things that people say but when the reaper is close then they usually want to push him off a little longer and have more life. Much like money maybe.

    Based on my relatively limited second-hand experience, it depends a lot on health and relationships. Some of my elderly relatives would have loved to live another 10 years, others would've been happy to have died quietly in their sleep 10 years earlier. My grandfather in particular lived to be in his mid 90s, and did not enjoy the last 10 years: outlived all his friends and his wife, couldn't really hear or see well enough to read, watch television, or carry on a conversation, could not walk, couldn't use the toilet without assistance, was on a bunch of painkillers for joint pain, etc. He was definitely of the opinion that there had been some kind of error and he was living past when his time was up.

      They wouldn't have been happy to die in their sleep 10 years earlier, they would have been dead. [grammar distinction]. Whether they would have prospectively desired at the time to die in their sleep 10 years earlier, on the other hand, is something we can objectively measure... because suicide is a thing that exists. Did they? Signs point to no.

        Suicide sort of occupies a different space with a strong stigma (and in many jurisdictions, legal barriers that can go as far as involuntarily committing someone to forcibly prevent them from committing suicide). Though that's culturally variable. There are many people who would not lift a finger to avoid a heart attack if they had the ability to do so, but who still would not actively kill themselves. A fairly common in-between is elderly people who choose to stay at home rather than go to the hospital, even if what they have is potentially treatable (they sometimes also have do-not-resuscitate and no-life-support orders entered, just in case someone takes them there).
