Aging is a natural part of life, but that hasn't stopped people from embarking on efforts to stop the process. Unfortunately, perhaps, those attempts are futile, according to University of Arizona researchers who have proved that it's mathematically impossible to halt aging in multicellular organisms like humans. "Aging is mathematically inevitable - like, seriously inevitable. There's logically, theoretically, mathematically no way out," said Joanna Masel, professor of ecology and evolutionary biology and at the UA.
Masel and UA postdoctoral researcher Paul Nelson outline their findings on math and aging in a new study titled "Intercellular Competition and Inevitability of Multicellular Aging," published in Proceedings of the National Academy of Sciences.
Current understanding of the evolution of aging leaves open the possibility that aging could be stopped if only science could figure out a way to make selection between organisms perfect. One way to do that might be to use competition between cells to eliminate poorly functioning "sluggish" cells linked to aging, while keeping other cells intact. However, the solution isn't that simple, Masel and Nelson say.
Two things happen to the body on a cellular level as it ages, Nelson explains. One is that cells slow down and start to lose function, like when your hair cells, for example, stop making pigment. The other thing that happens is that some cells crank up their growth rate, which can cause cancer cells to form. As we get older, we all tend, at some point, to develop cancer cells in the body, even if they're not causing symptoms, the researchers say. Masel and Nelson found that even if natural selection were perfect, aging would still occur, since cancer cells tend to cheat when cells compete.

[Abstract]: Intercellular competition and the inevitability of multicellular aging
So, either you die of old age or you die of cancer. Choose wisely !!

Cryonics is making a gamble on future medical capabilities becoming much more advanced than today's, including the ability to safely unfreeze a cryoprotectant filled meatbag and reverse recent death. If you lose the bet and never get defrosted or revival doesn't work, you were going to die anyway. So it's a good bet.
Contrary to what the dumb article would have you believe, anti-aging and regenerative medicine are possible. Those will also advance greatly by the time popsicles start to get defrosted.

Yeah. That was the phrase I was looking for.
are possible
Perhaps. I won't be holding my breath.
...and I don't see coming back after everyone you know is dead and everything you know is useless as a great enticement.

It depends on your motivations. Maybe you're massively antisocial and more interested in new knowledge and science than old relationships. You could also make connections with new people, a fresh start.
Maybe you plan to be frozen as a family, one at a time [bbc.com].
