Live Forever?

[Guest zagen]

Do you want to Live Forever?

 

Yes, it's a joke webpage, you've probably heard of it a long time ago, and it's a far fetched Idea, but is it possible? Has anyone read much or know much about the theories of cells dying? The "celular clock" theory has been around, but I dont think it's highly regarded. Is it all about the heart weakening or other things malfunctioning? Why does this happen? just because of cellular breakdown, clogged aurteries, and sudden weakness of the heart muscle? Are there many studies being done, and if so what are the theories?

 

I don't mean is it just possible for this guy's idea to work, but is it actually theoretically possible to live forever?

[Cap'n Refsmmat]

Not possible. Magnets have no affect on humans except the placebo effect.

[YT2095]

Hmmm.. not entirely true.

fixed magnets commercialy available that they sell as "heal everything" jobbies are as cap says, placebo effect. however magnetic feilds esp at osscilation can be devastating biologicaly in the EM sense. and they effect us passively too, else MRI scans wouldn`t work

[Cap'n Refsmmat]

Don't call me "cap"!

MRIs don't affect us much, they are scanning to see inside us. So they don't really affect us (unless your credit card is in your pocket! goodbye credit card!)

I thought life ends because the shortening of telomeres results in taking away of our essential alleles.

I think reptiles only grow larger as they age, they don't get older like mamals. Thats way some turtles can live for hundreds of years. Why can't people be that way?

[fafalone]

One of the primary causes of aging in the erosion of the telomeres into functional genes. Every time DNA is copied, a little bit at the very end is lost in the region called the telomere. Telomerase in the enzyme that repairs these, but eventually its levels decline and parts of functional genes get cut off. If we could increase the telemerase levels, we could easily extend life by a few decades; it's been done in rats resulting in 3x the normal life span. Granted this is not forever, but its a step towards it.

Turtles don't do very much...

[Cap'n Refsmmat]

They do get old, they just have a good lifestyle. Just slowly strolling around, munching on some grass...

[-Demosthenes-]

I think I read that some reptiles are born mature, and only grow larger. The never age, or mature normal. The only change they go through life is that they get bigger.

[Cap'n Refsmmat]

And then die.

[-Demosthenes-]

Everything dies eventually.

... unless nothing kills it, including itself and aging by loss of telomeres.

 

i heard that trees don't have telomeres, and they don't need them somehow. this would likely mean that some outside influence has to kill them, and would explain the rare, but very real 5,000 year old trees.

[Cap'n Refsmmat]

That would explain it. Something gets to them eventually, like fungus.

[-Demosthenes-]

So if we could keep a tree in a steralized place it would live forever?

[Cap'n Refsmmat]

And you gave it nutrients, I suppose so. But who would spend the time to find out?

Look at reply #7

"Every time DNA is copied, a little bit at the very end is lost in the region called the telomere."

Won't that happen??

[Guest Arenageth]

Hi i may be new here and i hope you dont mind me posting this. But i read that there is a part in the DNA that when isolated and taken out can stop the aging prosses. But im a little sceptial as most people would be but then i remember that there is a gene in our body that is a A.K.A selfdestruct gene that can triger tumas. so i fugure its possible.

[Cap'n Refsmmat]

You won't live forever unless you can cure every disease and injury known to mankind. That is the major problem.

[BrainMan]

however magnetic feilds esp at osscilation can be devastating biologicaly in the EM sense.

 

Transcrainial magnetic stimulation can do all sorts of strange things to a person's mind.

Huh???

[DeoxyriboNucleicAcid]

I assume you mean in trees, well Im not quite sure. But anyway, I have heard that humans have many many "waste" or extra genes. So if we increased the amount of extra genes in DNA, we could extend the amount of time it takes for the DNA to ware down when undergoing mitosis, and possibly live longer???

This may sound crazy, please correct me if I am wrong, ad forgive me if this is obserd, I dont take AP bio till next year :-D

[-Demosthenes-]

You can't just change someones DNA, can you? If you did wouldn't you have to do it to the single cell that they were before they were born?

[Cap'n Refsmmat]

Make a virus that constantly invades their cells and modifies the DNA.

I don't think that would work. Extra DNA can cause problems. For instance, Down's syndrone is caused by an extra copy of chromosome 21. Even if you're just adding "waste" DNA, it could still affect regulation of functioning genes.
