It’s a question that many of us ask from time to time, and one that has no right or wrong answer. History tells us that we are now living two and three times longer than our ancestors did only centuries ago. Living to be over 100, while incredible to family members, no longer gets a second glance from the general public or the newspapers. As it stands, the oldest known human on Earth is a 114 year young woman named Edna Parker in Indiana, USA. But what if 114 could become the next 30?
Researchers at Kyoto University have recently discovered how to create biologically compatible stemcells from our skin. This process, while incredibly exciting, could lead to a drastic change in the human condition and create lasting repercussions on our societies, cultures and social structures. For all the ethical dilemmas this process has solved, it opens the doors to so many more.
Professor Shinya Yamanaka at Kyoto University explains that the procedure that converts our healthy epidermal cells to those that mimic the incredibly dynamic stem cells is both painless and quick. For the moment, this is limited only to creating neurons and heart tissues (both very important), but this limitation won’t last long. Once the cells are cultivated, they can be given specific instructions and injected back into our bodies. This could also potentially provide cures to various cancers, AIDS, Alzheimer’s, Parkinson’s, and many other debilitating diseases and conditions. Once perfected, we will have the ability to repair damaged organs, joints, muscles and any other tissue. Heck, it might even be possible to regrow limbs under the right conditions. With applications like this, what’s going to stop us from finding ways to increase our limited lifetimes to something a little less finite?
It’s no secret that we fear our own death, and many also worry about losing those close to us. So wouldn’t life be so much more enjoyable if we could live for five or six centuries? If we can repair hideously debilitating diseases, what’s to stop us from reversing the aging process? Given the resources, our parents and grandparents could regain some of the things age has taken away. I don’t know about you, but if I could live for a few centuries with the same levels of mobility and health as I have now, then I’d be hard pressed not to sign up.
There are some problems, though. If nobody is dying, then we will have a serious resource problem on our hands. Little issues like whether we should exploit national preservation parks or untamed continents will become moot as we scramble to accommodate a hyper actively growing population. Retirement would become a thing of the past as everyone could essentially stay at a company for centuries, making it impossible for new recruits to rise through the ranks to leadership and breeding contempt for our elders. Land values would skyrocket further as there would be no inherited properties unless an accident occurred. Transportation systems would become overloaded as never before in the space of one generation.
It would be a massive logistics headache that would not only change our existing relationship with the Earth, but the very foundations of our societies.
One area I’m not too sure about, though, is how well something like a 500-year lifespan would be received by the religious communities. Would extending our life cross the line between medicine and playing God? As it is, humans are playing God everyday as we search to unlock the mysteries of the universe and everything contained within. This could be the very thing that makes or breaks the massive legions of religious followers. “God promises eternal life. Science promises a few centuries in exchange for a good chunk of money. Make your choice.”
Will any god accept us if we modify our bodies to escape the unescapable? Can reincarnation occur if we never die? Of course, if time is not a factor in the reincarnation process, then this is not an issue.
Of course, much of this is just speculation. I’ve read far too many science fiction books that have used a modified cure for cancer and AIDS as the precursor to semi-immortal humans. We wouldn’t be impervious to death, of course. But we would be biologically capable of living hundreds of years before growing tired of life.
Personally, I don’t want to live forever. One or two hundred years max, and that’s only if I remain mobile. I refuse to spend the last of my days in an old-age home. How about you? How long is ‘long enough’?
