Five Science Facts That Will Blow Your Mind

[Hoofbite]

Those are facts?

 

[Hoofbite]

Let me just say I don't buy into this so called science facts either

As for living 1,000 years even if it could be done is it worth it? Stop and think of an already over crowed world we have now.

Never been to Wyoming, huh?

Why? :laugh2:

Actually, I do want to go to Wyoming. (Jackson Hole / Yosemite National Park)

I don't see it happening. You can't prevent aging completely. Just because someone finds a way to rejuvenate skin or something like that, the heart, lungs, kidneys etc age too. Not to mention plaque (not teeth, in arteries) build ups, etc and even diseases of different types will kill you first. (heart disease or something similar) That isn't even talking about the deterioration of the brain. Not only from age, but from what people do to themselves.

1,000 year ain't happening. Maybe 150s, but at that point the overcrowding and pollution issues will become so bad that they will start up a Logan's Run scenario.

I think part of the idea is to prevent all that stuff you talked about......not just outlast it.

Because Wyoming will kill any idea of overcrowding.

Anyone who drives through Wyoming and isn't screaming for human contact of some sort, be it a jerk driver or decent-sized town, is out of their mind.

That being said, I've recently tried rewatching Highlander the tv show and the movie, and both were terribly, terribly campy. Especially the movie, I had to turn it off.

A lot of old TV shows are that way. I tried to watch The Incredible Hulk and even the A-Team. It was like trying to play the Pong again after playing all of todays games.

SUCKS!

Who would want to live to be 150 to 200?

Who would want to live to be 150 to 200?

Depends on what I have going on at the time.

Who would want to live to be 150 to 200?

People who are willing to clone themselves even though that doesn't mean they don't die, just that their replica will live. It's like a twin who was born xx years after you.

Gotta love BS. This reminds me of the guy who predicted the world's end a few weeks ago. I guess his magic 8 ball was broke! Or maybe his hologram wasn't coming in clear.

BTW I think doctors can diagnose some diseases by smelling, diarrhia comes to mind.

I can think of any number of congressmen or senators who would like the idea. Some even have a pretty good head start on it.

Looks like a couple currently untestable hypotheses there with the 2nd (unless it's just referring to the cornea/brain) and 4th listed items. Also not mind-blowing as I've already had my mind blown by reading that type of philosophy years ago.

The 1000 year old human will be possible. Probably a combination of stem cells, nanotech, and biomechanics/bioengineering. Only some spawn of a wealthy person will be able to afford these things, though.

Don't know that they'll make it to 1,000, but it'll be possible if their support system stays connected and they can avoid dying from things like a nuclear holocaust, alien invasion, murdered by spouse, meteor strike, plane crash, robot attack, etc.

I watched a show on the History Channel that talked about this. As long as our cells reproduce normally we don't age as fast. But there comes a time when the cells don't reproduce and then we age rapidly. What causes the cell to quit reproducing is interesting. Each chromosome has a cap on each end of it called a telomere. The telomer doesn't fully replicate itself each time the cell replicates and thus keeps getting shorter and shorter over time. When the telomere is completely gone the chromosome ends start to fray and it can't replicate. The telomere is like the plastic tip on the end of a shoelace that keeps is from fraying.

Cancer cells have long telomeres that don't shorten when it replicates. That why they don't die a normal death.

Scientists are researching a substance that keeps the telomers of normal cells from dying off, which could extend our age to 180 or 200 years. They have to walk the tightrope though because they could turn the cells into cancer cells.

At least, that is the way I understood the show.

The telomere is often also referred to as a "poly-A tail." At the end of a genetic sequence there are repeating series of AAA AAA AAA AAA that continue on for a finite length depending on the cell. As the cell replicates, one of the codons gets lopped off. Once you reach the end point, the cell lineage dies.

The trick isn't just having the poly A tail fail to cleave at the end of the DNA replication process, but to have that one cell divide and the better of the parent and daughter cell survive if there is any differentiation in the genetic code between the two.

And 1000 years? Not unreasonable. A professor at Alabama-Birmingham had taken cat (and now horse as well I believe) somatic tissue samples which had a life expectancy ex-vitro of approximately 3 weeks and had the tissue still alive and fully functioning 2 years after the start of the experiment. That translates to a 34x increase in life span for that particular tissue type.

That said, getting a tissue culture to stay alive and functioning for 34x the normal life expectancy and then translating it fully to an advance mammal to increase the experimental subject's life expectancy in any capacity would be the same as Pasteur telling the world he found a way to curtail infection after a surgery, then expecting him to perform a liver transplant with 100% success rate. The two things are not inherently equal achievements nor are they translatable feats of genetic manipulation. Not by a damn sight.

The 1000 year hypothesis might be in reference to our ability to engineer new parts and pieces for a person as the old ones wear out. The life expectancy of a mammal, and some other animal types, is governed by what is loosely referred to as the "Million Heartbeats Rule". Looking at the overall population of a given species and/or as defined a subspecies as the experiment wishes to delineate, you then look at the amount of time it takes for each individual within that population to have reached one million heartbeats. The elapsed time of the million mark gives you a general idea of the life expectancy, all things being equal.

Of course the life expectancy can be hugely optimized by favorable environmental factors, and the overall life expectancy of a population can be artificially extended by selectively choosing the individuals within the phylogeny of the population that has the longest lifespan, and then only allowing those individuals of both sexes to breed. It's a multi-step generational approach that has been successfully tested in a variety of short-life span animals such as good old Drosophila melanogaster and the common lab mouse. There is of course a point at which life cannot be extended without additional manipulation of the population's genetics beyond artificial selection.

So what you have then is a point at which most of an animal's systems begin to break down. As long as you can engineer replacements for everything that supports the CNS, you can extend life indefinitely. Finding solutions for diseases that affect the CNS is your Holy Grail.

Keep the mind healthy, engineer the supporting organs and systems, and you've got the recipe for a 1000+ year life span.

So simple, in theory.

Of the original 5 point list as shown by the original post; #1, 3 and 5 are the most likely. However they are presented in the bulleted form to strike your attention much like Ripley's Believe It or Not would have done.

Smelling a disease? Perhaps a misrepresentation of the respiratory properties of a diseased cell or tissue set. Put a person in a controlled environment and by judging what their exhaled gas mixture is you could present a possible diagnosis of the disease if you had a full baseline to start from. For years certain 'smells' of a person's breath were indicators of diseases.

Ever so slightly fermenting apples? A sign of an infected appendix. There are also diagnostic smells of other conditions that include smells of certain fruity cheese smells for strep throat, hints of acetone for something, and there's one more but I'd have to go hunting in Taber's to find it.

Ironic, isn't it?

By trying to avoid death through cloning, you're actually subjecting yourself to numerous deaths.

Anyone ever read this short story called Learning to be me by Egan? It's about a time in the future where our brain (which will eventually fail) is implanted close to birth with a chip that learns exactly what you do and think and say. Basically, a replica of your brain. When you reach a certain age, the brain is disposed of. In that case, this chip takes over, and is you...for a very long time. Would you say it is still "you" if it would have done everything you would have done?

And then there's the paradox regarding how many replacements will it no longer be "you." Think of the classical example, a ship. Let's say you replace a board on a Ship A. Is it still Ship A? What if you gradually started to replace every single board, material, etc on Ship A. When does it cease to be Ship A? And if it does, if you reassemble all the throwaway materials to make another ship, is that Ship A?
