In the past 200 years, the average life expectancy on Earth has more than doubled. But despite being able to live longer, we still haven’t figured out a way to stop aging.The very idea of conquering age sounds impossible, not to mention unnatural. But don’t act like you wouldn’t want that sweet, sweet victory. At 25, you’re at your physical best. At 40, your body starts getting weaker.Does that sound fair to you?Based on what aging is, it seems that it’s only a matter of time before we’re able to slow its effects, if not stop it completely. After all, aging is simply a biological process. It’s what happens when your body can no longer keep up with repairing your weakened and damaged cells.You’ll also have free radicals to deal with. And no, we are not referring to counter-cultural leftist youths who aggravate older people! Free radicals are unstable atoms that your body naturally produces, and they’ve been proven to damage cells. The resulting cell damage can lead to a range of diseases that are typically linked to old age.If we get to an age we really like, and then stop our body from making free radicals, our cellular and molecular structure wouldn’t age as much. And that might just be our ticket to eternal youth.But while that might sound like good news to you, ask yourself, is anti-aging good for the Earth and all the people on it?You can imagine how the world would be a much happier place if we never aged. Generally speaking, we would have a healthier population. Fewer people would experience the chronic pain that comes with old age, and we’d see an end to age-related diseases such as Alzheimers, dementia and Parkinson’s.Families could expect to pay fewer medical costs, providing the healthcare system with some much-needed relief. More people might live on to meet their great-great-grandchildren, and even their great-great-great-grandchildren.An ageless world would be a utopia! You could get so much more out of life, crossing off all the items on your bucket list without feeling weak, or tired, or worrying about how much time you had left. Barring other causes of death like accidents or illnesses, you might even be able to live forever! But in what kind of world?We might stop aging, but we wouldn’t stop reproducing. The world would quickly become a claustrophobic place. Earth’s population would boom, and we’d find ourselves increasingly strained to find enough space for everybody. Safe and comfortable housing wouldn’t be the only problem. How would we feed everybody? Our quality of life would become increasingly unaffordable, as a world without aging would mean a world with fewer retirees.Newcomers to the workforce would struggle to earn a living, and this would be made worse by job cuts in medicine and funeral services, as well as the cosmetics industry. To give you an idea of how devastating that would be, just consider that the US funeral industry alone adds approximately 20 billion dollars to the national economy every year.As individuals, food, shelter, and how to pay for them would be some of our top concerns. But how about the planet as a whole?Earth has a threshold for how many lives it can support. So if we stopped aging, we’d quickly use up our world’s resources, making the climate crisis so much worse that we might soon find ourselves wishing we could grow old, just to speed ourselves out of this nightmare.The thing to remember is that aging and death, while unpleasant, are natural processes. Even if we don’t like growing old and phasing out, humanity, as a species, needs it. While we grow old, Earth is constantly rejuvenating itself through evolution. Every organism on the planet must one day leave to make room for new and healthier organisms.This is how the world has stayed young and fit for billions of years! So while you might not like growing old, be proud of the fact that growing old and phasing out is part of a bigger process to keep the Earth young and healthy, so that it can continue to support generations of humans who will get to enjoy life as much as you have!Of course, it would be nice to stay young for a little longer, and there are plenty of scientists who are researching ways to make it possible. The SENS Research Foundation, for example, is working on an anti-aging project called rejuvenation biotechnology, which would reverse the effects of aging without halting the process altogether. Not good enough? Still feel like living forever?
