Unless you could stop the aging process at a specific age then what's the point living "forever" if your body keeps getting older, I mean who wants to be 200yo but with the body of a 200yo?
Yeah, and considering many of us already end up pooing ourselves in a care home in what can only be described as an existence of pure misery living forever wouldn't be great.
the brains into. Against various rights but that'll all be changed if it becomes possible the super wealthy have a way to live extended lives. Also probably easier than immortality in the same body due to the wear and tear. Oxygen is key to human life but is also an aging factor on the body too. Being 150 years old and arthritis in most joints, including spine, would be no fun at all either.
