Steven Johnson: How humanity doubled life expectancy in a century | TED
Doubling human life expectancy in a century is our greatest achievement, says author Steven Johnson. How did we make it happen — and can we keep it going? Backed by fascinating historical anecdotes, he shares some life-lengthening innovations and reminds us of three key things needed to make sure all of humanity enjoys these advancements…

Not dying while young a great achievement. Longer lives when you are old and infirm is far less good for society when the common resources are used to make it happen by centrally planned force. Turns out more free people likely matches this trend of longer lives. If you want to give credit to big government, then you need to subtract out the death, injuries, property destruction, mental disorders and mal-directed dollars for their wars. And of course for not following the prior FDA food pyramids.

Whilst life expectancy has increased … remember that if childhood disease did not kill you, then you could expect to live to 40+, and if adult disease, childbirth, war, or work accident did not kill you then you could expect to live to 75 easily … the oldest person in 1900 was over 110, the oldest people today are also just over 110 … there are just more of them

Let me guess. By first reducing it to half? … Are we counting the life expectancy of collonialised indigenous people who we westeners violate to create our super civilized high life expectancy states? I guess theirs hasn’t changed much in that time. Are we counting the life expectancy of sentient life which has feelings? As far as i know we kill billions of animals similar to us at an age equivalent to a child or a teenager. Sure. Let’s reduce our sample set and perspective to a tiny narcissistic point and have party for how cool we are. Sorry, but F that.

That London mortality chart from the 1840s at 2:39 is pretty harrowing. Over one-third dead by the age of 5, another 10% dead by 20 – only 3 out of 5 people in that generation made it to adulthood. Only half of the generation makes it to age 40.

On the topic of aging, I was inspired to take my own journey from podcasts of Dr. David Sinclair who is a world-renounced Biologist of Aging Research at Harvard Medical School:
*My NAD+ experience*
Some quick background: NAD+ is is a form of vitamin B3 and naturally produced naturally in the body either by fasting or by exercising. NAD+ helps maintain cellular health against everyday stressors, it improves cellular function and metabolism, and a lot more. Wtf does this have to do with TELEMERES? NAD+ is required for functioning of the sirtuin proteins that help maintain the length of telomeres!
Here’s my personal experience taking it for 18+ months.
I know my evidence might be just anecdotal, but I’ve been taking a precursor to NAD+ called Nicotinamide Riboside at a 300mg daily dose orally for 3 months (I started May 9th 2020 and these were my benefits 3 months later and onwards). My current biological age is 20 years old but after the 3 month period I was 19. Here’s my timeline so far in terms of benefits:
Since my start, it took my body 2 and a half weeks to adapt to the change and feel any benefits but then I woke up one day roughly 2 weeks later and had plenty of energy. This baffled me since that night I only got 5 hours of sleep. With all of this energy, I wasn’t hyper but more clearer-minded and restful. I would go as far as to say I felt like I had the same energy as I did when I was 12.
After those 2 and a half weeks, the next big change for me was constantly dreaming. For 9 straight days, I had at least 2 dreams per night which was unheard of for me and I was low key excited for what would happen next. During this time, I noticed how after lunchtime around midday, I didn’t have a drop in energy. Previously, I had attended school and as soon as my lunch break had ended and I made it to the next period, I used to get a wave of lethargy and often dozed off to sleep for a quick power nap. What happened next really changed me. Due to my sleep schedule fixing itself gradually, my circadian rhythm was fixing itself and I had begun to feel tired earlier which took me by surprise.
Following this abundant change, about a week later I noticed that I would watch Netflix shows and YouTube in a whole different way. Before this experiment for myself, I would most of the time watch a show and remember some details unless something drastic happened in what I was watching or doing in general but something changed. My memory of recollecting what had happened was so much better as now I wouldn’t just remember minor details but I would be able to remember the characters names even a couple months after watching the show. In my day-to-day life, my improved memory helped me remember orders I would write down since I’m the “Uber Eats” for the family, driving to and from restaurants and picking up food for us.
I know this is all anecdotal evidence and it’s not concrete evidence but these have been the benefits 18 months into taking this NAD+ booster as supplementation. Since the start, these benefits felt like they have compounded as I feel incredible! Anyways, I’ve been taking this supplement which is a form of vitamin B3 (Nicotinamide Riboside: NR) ever since and it’s been well over a year and a half nonstop and I have no long term side effects.
Feel free to ask me any questions at all about anything I mentioned or if you’re curious about anything! Since the start, these benefits felt like they have compounded as I feel incredible! Thanks for reading the script for my YouTube comment Ted Talk 🙂

Wow the arrogance of so called science. We don’t have longer lifespan because of modern medicine. It’s weird how he never adresses the causes of what he is explaining. First off vaccines do not address the root cause of the outbreak, as most if not all of our pandemics in all of human history have been created by our bad habits, mainly thru animals farming, or thru the animal trade, or hunting them and destroying their habitat. The reason milk from a cow killed so many infants was not because of a lack of pasteurization, it is because it is not their milk, it wasn’t designed for humans, it was designed for ta baby calf that the cow just gave birth to Humans are the only animal on this planet who drinks milk after they been weened from their mother, that is just weird. A lot of our outbreaks also came from bad sanitation, like polio, colora, and malaria, the more you soil your environment, the more illness you have. Right now what is ailing people are chemicals that are put in the food supply like pesticides, herbicides, fungicides, and added chemicals in their pre-made foods. They are also suffering from all of the chemicals and microplastics that industry is spewing out into the environment. Also one of the reason we die later in life is that we do patch work for our biggest killer of human being called heart disease which is mainly caused by ingesting animal products with saturated fats and cholesterol. If we want to live healthy until old age we need to clean up our habits that are destroying this planet.

On the Occasion of International Human Rights Day
(December 10, 2021)
—
We must say openly
to each other the things we hold in our hearts and that too often are
said only behind closed doors.
There must be a sustained effort
to
listen to each other;
to learn from each other;
to respect one another;
and to seek common ground.
As the Holy Koran tells us, “Be conscious
of God and speak always the truth.”
That is what I will try
to do today — to speak the truth as best I can,
humbled by the task
before us,
and firm in my belief that the interests we share as human
beings are far more powerful than the forces that drive us apart.
These are not just
United Nations | الأمـــــمُ المتّـحــــدَة
ideas,
they are human rights.
And that is why we will support them everywhere.
Thank you.
And May God’s peace 🌏 be upon you all.
Thank you.

This is one of the benefits and costs of long-term economic growth and societal progression. As a group, we just need to negotiate other factors so we aren’t overwhelmed by the health system we created. Specifically, each and every one of us can help by reducing our individual waste and not taking more food than we need, and we can start on the climate by picking one piece of trash we see per day. Your conscience will do the rest. Wish you all luck,

The main contributors to climate change where regular humans play a part are power generation, agriculture(particularly livestock) & transport. Of these realistically the only thing we can really make a meaningful difference to is agriculture, by changing our diets.

I’m strongly on the pro-indefinite lifespans train. If we get some regulatory framework that stops indefinite lifespans from occurring or even intentionally slows their development then that government is murdering its citizens.
We do need institutional innovation but it should be focused on how to spread indefinite lifespans to everyone who wants them and how to manage the changes in society it causes, not some awful system where there’s a vote on whether researchers are allowed to develop a drug to help treat grampa’s age related heart disease.

Imagine people waking up to go on a walk, instead of a cup of coffee, and we can walk away from toxic materials and products we use in today’s standards.

Really liked this video but it’s a shame that access to cheap energy (ie. Fossil fuel burning) was missed out as it underlies all these other changes and has an almost 1:1 mapping onto life expectancy. It allowed us to outsource most grinding labour to machines, bought us time to work in scientific and bureaucratic institutions (as opposed to most people working in subsistence agriculture) and powered industries such as manufacturing, vaccine production milk pasteurization. It also improved food security (through fertilizers) and resilience to natural / climate disasters. Of course we all know that fossil fuels come with their own problems, but let’s not pretend that we’d have any of the amazing breakthroughs you mentioned in this video without them.
