Human life is finite and will eventually end. Since it's not possible to find a way of escaping death, the only real choice is how one wants to live out their life before they die. Enjoying a lifetime with limited time seems daunting and perhaps depressing but that is flow of time and human life. It is how we choose to spend these days that makes the looming proposition of an imminent end dissipate. One can't exactly enjoy time if we're worried all the time, that something bad is going to happen and you'll be unable to stop it. And so we progress with optimism and productivity.
So what's the point of life when it can be taken away at any time? That is a question that goes deep into philosophy. A person’s calling is sometimes a journey in itself and this is why, despite our lives being a limited commodity, we can appreciate the experiences it brings us throughout.
Recently, a ground breaking piece of research in oxygen therapy has yielded great results in biological aging reversal. To summarise, it involves using pressurized oxygen chambers to reduce cell production related to aging, turning back biological clocks. I might call this more of a life extension than reversal but perhaps that’s just semantics.
I believe that extending (beyond humanity) is a matter of unknown territory. It's not a bad idea, because it isn't an idea at all. The problem is that there is no definition of extending life, so it's impossible to understand at this point in time. How long the average human would live and perhaps the quality of life change when undergoing such treatment along with other consideration. Let's say for example that we decide to extend life spans indefinitely, what does this mean? Does it mean that everyone gets immortality or only a select few do? If only a select few do, the majority will be unhappy. Are we going to force this ‘happiness’ upon everyone?
Now let us imagine that we all attain immortality. One can only imagine the implications with this as the world itself is finite in resource. So perhaps before making humanity immortal, an effort to realise reversing or immortal effects on our very mortal planet is needed first.
