Science!

quantum communicators have already been done its been in the news both in Canada and china and in the us and at cern all have done the experiments and all have proven they work even if its only a couple of data bits at a time there already making FTL communications, more people and more money would allow them to conduct the experiments over greater distances and permit them to have two way instead of one way, strangely after the successful results in the test run in Canada were published university groups across the us and the uk have announced plans to create their own quantum hubs that link themselves and each other together to the hub already built in Canada and of course as expected the banks and international finance house are providing the bulk of the funding to help them achieve this stuff.

as to magnetic fields, what exactly do you think gravity is how is it created ?

I'll give you a clue its not centrifugal force, that would toss everything (and everyone) to the outside edge of the planet

Yes, quality of life is a huge concern once you get 50+. Physically, mentally/emotionally, very few people are aware of the all encompassing issues of paying for a failing body, lower mobility, isolation and loneliness. 

In fact- one of the reasons why I love the book Forever War is how much it demonstrates the impact of time dilation in space travel and how lost the protag feels eventually. I imagine this is how it might feel as someone that lives to 100+ where all of his or her peers have gone the way of average mortals and they are left alone on the apex of life span in a sea of strangers in a strange land transformed by time. 

I totally hear you. Unfortunately at that point you would be deemed not competent to make your own health choices, so you'd be better off choosing assisted suicide while you are still yourself rather than waiting. That also avoids the guilt your husband and children would feel if they had to be the ones deciding when to pull the plug on you (rather than you making the decision for yourself). If human euthanasia becomes widespread there will be many thorny issues to deal with such as "I made a directive when I was healthy that I wanted to be euthanized if I became incompetent, but now that I'm incompetent I may claim I no longer want that and now what?"

One issue I see with living longer is that people can't make enough money by the time they reach retirement age to support themselves for the rest of their lives. If my working life is from 25 to 65 (40 years), how am I supposed to save enough to support myself and my chronic diseases from age 65 to 95 or beyond? And currently no one wants to hire 70 year olds. It would be great if we could add prime years to our lives so most people could continue working into their 70s and 80s if they wanted (or needed) to instead of just tacking time on to the end of our lives. I guess I'm going to have to learn to make things to sell on Etsy to supplement my meager savings and social security (if there is any at that point).

Naturally? Of course not, our bodies have limits, imperfect copies replacing even more imperfect copies in a infinite loop until death. Yet that said we have barely scratched the surface of actual implementation of cellular manipulation and augmentation. The Human Genome Project remains to my knowledge the last great leap before the drop off, now we study it for individual illnesses and cancers, we don't have coordinated efforts between nations on how to approach matter mortality. There have been dozens of proposed concepts that theoretically could increase lifespan well beyond what we would consider a natural limit. But the technology doesn't exist to take us there, and the tech doesn't exist because the research doesn't exist to prove or disprove concepts.

And with all these rulings by the UN forbidding genetic engineering and all the ethical concerns of it, it will never happen until this political climate actually changes.
