There are many advances on different fronts in this area, for example telomere shortening.

Also considering that once we sequence our genes we could create new organs, etc, the only risk will be the proverbial bus.

Well, in regard to your fourth "method" of becoming biologically immortal, I read something a while ago about some scientists that effectively stopped aging in mice livers.  Basically, as people (and mice, apparently) become older, their cells become less efficient in many ways, including the cleaning up of sometimes damaged protein.  This can lead to the buildup of toxic materials in these cells; this buildup is especially pronounced in diseases whose symptoms are mostly acquired in old age, such as Alzheimer's, Parkinson's, and more. 

These scientists also found that more protein clearance helps prevent some of the "old-age" declines in function in mice.

Thus, if findings show that there are ways to enhance protein cleanup in humans using specific drugs or other methods, we may be able to use this same cleaning process in human livers and other organs and may well stave off the process of aging for a little while. 

There are other options that I've read about, some involving stem cells, telomere shortening as mentioned above, and more. 

With all these exciting advances, biological immortality may be achievable in the next few generations.  The real question is, do we want it?

Really? I think I read something in 'Time' magazine that that'd be available by 2045... I'm not exactly sure that's just what I read on the cover. Then again, I don't even plan on being alive by that decade!

2050 just to be safe. Probably 2030 I suppose. Tigeree, even if you die, you can be cryogenically frozen in nitrogen oxide and possibly revived later.

Such as?

Hi CT;

Welcome to the forum! And now for a another view of eternal life.

With the recent failure of the worlds medical profession to deal with the rising number of pathogens that are almost totally resistant to their antibiotics I do not think we will ever have to examine the consequences or benefits of immortality.

An alarming number of diseases that are now pandemic, freakish storms and earthquakes where there are not supposed to be any. Total exhaustion of the worlds topsoil and resources. Oxygen levels dropping and bottoming out in US cities coupled with gruesome predictions such as the Georgia guidestone. I do not think immortality is in the cards, but rather we will be more aware of our mortality in the near future.

Hi CT;

I was not even thinking about that that. I will look for a more svelte individual as my avatar.

Unfortunately, I am well aware of the side effects of modern medicine. As far as antibiotics are concerned there is nothing but the side effects.

Those are just some of the problems. We have no clean water or uncontaminated food to drink or eat.

Hi;

The experts on it are mostly dead. During WWII the Nazis conducted the best research on freezing animals and people. Since they had no qualms or cares about the test subjects they were able to do things other researchers could not. They amassed a huge amount of info in the field and most of it was captured by the US and USSR. Even today most of the results remain hidden.

Not likely, pathogens evolve too. They overcome the defenses that organisms have. Take the new MRSA, colors itself to escape detection, resistant to all antibiotics.

Hi;

The MRSA is immune to some antibiotics

If you are ever unlucky enough to have a run away case of it then you will find out that the above quote is not true. They literally poured them into me. The whole gamut of them. MRSA just laughed.

Funny thing is the main weapon against them is Bactrim which is nothing but a Sulfanilamide. Those were being used prior to WWII and were replaced by penicillin! That and a 2 week stay in the hospital where your doc will admit you have a 20% chance of not coming out. From an infection of a hangnail! The hospital staff felt 20% was a little low.

Oh and by the way, the number one place to catch MRSA is in a hospital! Just another skeleton that modern science is sweeping under the rug.

As far as we are told there is no evidence of any complex lifeform that is immortal anywhere in the world.

Now if you want to talk about the lunatic fringe...

Hi;

Nope! Only Vancomycin ( it is the last line of defence ) which must be delivered intravenously has around a 70% chance of arresting the infection. My mom got it from her hospital stay. If they can not eliminate it...

The point is that to many microorganisms humans are just a link in the food chain. If you have studied simplistic predator-prey models then you know if the prey population goes up then so does the predator population.

Hi;

She is gone a couple of years now but not from that infection.
