Humans, just like every other life form on Earth, inevitably die once they reach a certain age. Aging is a seemingly irreversible process of life that humankind has been trying to evade since the dawn of our existence, but is true immortality actually possible to achieve, or will it only ever exist in science fiction?
An interesting question, and you’ll undoubtedly receive a plethora of different answers depending on who you ask, but all clear indicators appear to suggest that immortality may not be impossible. In fact, recent scientific advances just might be pushing the theoretical life expectancy limit of 125 years on and up to 145 years.
Novel anti-aging drugs such as rapamycin are demonstrating longer lifespans in lab mice, and scientists think it would have a similar impact on humans. More importantly, organ failures could be easily averted with new 3D printing techniques, as new organs could be manufactured to replace those on the verge of failing.
Obviously, these are only small differences in projected lifespan, but some objectives are trying to go the whole nine yards and achieve full immortality. Some involve building specially-crafted bodies that would live long beyond the traditional lifespan of an average human, while others include freezing your brain to be transferred to a robotic vessel sometime in the distant future.
Achieving immortality probably won’t happen for a long time to come, perhaps not even until generations from today, but at least we can rely on modern medicines to increase our lifespan such that we make the best of it.
