The earth would be too crowded if we have immortality. We have enough problem competing for resources as it is. So thanks but no thanks.

That's not what I've seen so far. My line of work put me in contact with people of all ages. I occasionally saw 90 year olds who could still walk, but that was the extent of their mobility, and they were rare. Of those rare birds who make it to their 90s and beyond, nearly all of them are barely mobile AT BEST. The essentials are still working to the extent that they can breathe, the heart is ticking, brain function may or may not be full, but the muscles, the sinew, the joints...all break down after a 7 or 8 or 9 decades.
Now if we are talking "eternal youth" vs. "eternal life", maybe that comes with another set of challenges (I'm still not sure I'd want), but if we are talking "eternal aging"....nah...not for me, thanks.

Any theories as to why they capped us at 100, but then punished us with being demented during the last 2 decades?

There have already been talks about brain transplants. Imagine if a human brain could be transplanted in a 20-year-old body? It may live forever.

Soon, if not already, human organs will able to be grown in a lab. It is already possible to grow them in a human body. The next transition will be to grow organs in a human body that can be harvested.

Growing embryos invitro, then implanting them in a surrogate for the specific purpose of organ harvesting, will be next. The surrogate might be a human, or a lab.

The embryo that is implanted will be modified and be clinically brain-dead. That is, it will need food and nutrients, but will not be technically ‘alive’ from our current medical standards. It can be allowed to ‘grow’ for several years until the parts are of sufficient size.

Organs can be harvested as they are needed. One kidney or lung, a piece of skin, or even part of a liver will be no problem to harvest. If you need a heart, simply unplug the machine, let the organism go dormant, and take the part. Wealthier people may want several clones to enable retrieval of these spare parts.

Once this becomes common place, entire rooms can be filled with these clones, waiting for their parts to be needed. All the DNA will be known. They can be slowly automatically rotated as to avoid bed sores, similar to a roasted chicken on a spit. All they would need is a source of nutrition while they wait for their ultimate purpose. They could be used for blood plasma and bone marrow donations while they wait.

It may not be immortality, but I think you could get quite a few more years out of a body by changing parts.

The earth is a big, big place. As it is, the entire world's 7 B people could fit in a city the size of Texas if it had the population density of NYC. So there's plenty of room.

Of course we already have the technology to limit population size - it's called birth control.

That's the best reason why we may never "cure" cancer . . . we probably won't need to.

Of course, there is the problem, of where too grow food for all those people. Much of the ground in the world is unusable due to mountains, etc.

I've met quite a few humans who could use a brain transplant. Or, more accurately, a brain implant...

Soylen Green.

What do you think they're going to do with all those "spare" body parts?

More seriously, I'm not terribly concerned about resources. Malthus penned his thoughts about how population growth would outstrip the planet's resources more than 200 years ago. He wasn't even close.

I also think population overcrowding is already basically taking care of itself with birthrates declining as wealth increases.

You also have to assume that immortality tech isn't something that's going to be freely available to everyone. The people who can pay to live forever are the very people who tend not to have many children.

It increasingly seems that way.

The recent discovery of gravitational waves means that everything we think of as solid is actually wobbling around like jello as the fabric of space time gets stretched and compressed by gravity. Once you imagine that, nothing seems real any more.

Scientists even set up a clever little experiment using lasers to show that it was true.

I've seen where irrigation can have amazing plant growth results in the desert.......massive desalination could (possibly) transform many areas.

I pride myself in keeping older cars and appliances "going and going" by understanding, often up front, how I will be able to access spare parts.

3D printing age may make this even easier going forward.

I have had similar thoughts about human beings, myself in particular. Would still have to avoid something like invasive cancer however...

We are already going down this road with routine replacement of deteriorated joints (ie hips/knees/shoulders etc.) with artificial "spares".

I often wonder how much of death is the person eventually giving up.

Sounds like a good business case to me for space colonization.

It requires no faith or even significant stretch of the imagination to envision technology advancing to the point that the entire electro-chemical pattern in your brain is mapped and stored in order to be reloaded into a lab grown host of such age you choose. Alternatively you may choose to remain inside a quantum processor with augmented sensory input.

50 years to 100 years out maybe? I may not make it, but some of your children may live in this time.

I happened to watch Never Let Me Go, a 2010 British movie with this theme based on a dystopian novel of the same name by Kazuo Ishiguro. The novel was fairly acclaimed, as well as the movie. It's a drama, so science fiction fans looking for an action movie should not bother.

By the way, I also discovered that this author's novel The Remains of the Day was the source for a movie of the same title. He's a British author living in England, and this explains the background of his novels.

Eternal aging? Please spare me.

You describe my father-in-law in his last few years. At the end, he once told my wife "I do not want to live so long". When you lose the mobility of the arms to the point you cannot scratch your nose, it's tough.

The reason that life expectancy has been improving was due to several factors, and modern medicine played a big role but it may not be as many expect.

Infant mortality is reduced. Infectious diseases are also no longer a major cause of death. When people get older, drugs help prevent strokes, and there are better treatments for acute symptoms. Many cancer patients get a few more years of life as a return for surgeries and miserable chemotherapy.

But other than the above, they cannot help much with the natural aging. When you can no longer swallow, they will insert tubes to keep you alive. Weak lung capacity? Put them on oxygen. That gets them a few more years.

I suspect not too many people hang around older people, particularly those in hospitals, recovery centers, or nursing homes to see for themselves. And some don't even want to go visit their parents or relatives. So, they stay in denial mode.
