In 7 years, humans might be able to live indefinitely, predicts Ray Kurzweil, a
While, as shown with creatures such as hydra and Planarian worms, it is indeed possible for a creature to be biologically immortal, these are animals which are physiologically very different from humans, and it is not known if something comparable will ever be possible for humans.
If things continue in the same trajectory, the year 2050 has been projected to be the benchmark for when we will achieve immortality. Here are a few interventions that may hold the key to securing our indefinite existence on mother earth.
That's because humans need cells to do things other than just divide and make new cells. For example, our red blood cells transport oxygen around the body. "We make cells commit to a function, and in doing that, they have to lose the ability to divide," Martínez said.
The 'immortal' jellyfish, Turritopsis dohrnii
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii.
Normally, as time passes, our cells undergo changes: Our DNA mutates, cells stop dividing, and harmful junk—by-products of cellular activity—builds up. All these processes together cause us to age.
कृप: परशुरामश्च सप्तैतै चिरजीविन:॥ सप्तैतान् संस्मरेन्नित्यं मार्कण्डेयमथाष्टमम्। जीवेद्वर्षशतं सोपि सर्वव्याधिविवर्जितः॥ The mantra states that the remembrance of the seven immortals (Ashwatthama, Mahabali, Vyasa, Hanuman, Vibhishana, Kripa and Parashurama) offers one freedom from ailments and longevity.
These are natural changes that occur while aging. They cannot be stopped but it is possible to slow the rate of these processes. This can be done by changing one's lifestyle (diet, exercise, etc). The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.
The current record for human lifespan is held by Jeanne Calment, who lived to be 122 years and 164 days old. While this is an impressive achievement, it is still far from the 300-year mark. In fact, there is currently no scientific evidence to suggest that it is possible for humans to live for such a long time.
Futurist Ray Kurzweil is still making waves years after his initial singularity claims as artificial intelligence continues to progress. With singularity milestones coming, Kurzweil believes immortality is achievable by 2030. Kurzweil's predictions are met with a healthy dose of skepticism.
Researchers estimate that the human body may not be capable of living more than 150 years. But dozens of companies and many researchers worldwide are exploring how our cells and DNA age. Mysteries like cellular senescence, telomere length, and DNA methylation hold the keys to our longevity.
At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
Just as our planet existed for over 4 billion years before humans appeared, it will last for another 4 billion to 5 billion years, long after it becomes uninhabitable for humans.
More reproduction followed, and more mistakes, the process repeating over billions of generations. Finally, Homo sapiens appeared. But we aren't the end of that story. Evolution won't stop with us, and we might even be evolving faster than ever.
For men, the group expects they will live to be 83 to 86 instead of the government's projection of 80 years average life expectancy in 2050. S. Jay Olshansky, co-author of the report, said a few extra years life might not sound important, but it will cost us socially and financially.
The oldest known age ever attained was by Jeanne Calment, a Frenchwoman who died in 1997 at the age of 122. Ms. Calment is also the only documented case of a person living past 120, which many scientists had pegged as the upper limit of the human lifespan.
The average life expectancy of baby boomers, Gen X, Millennials, and Gen Z are different. Compared to the 70-year life expectancy of baby boomers and the 85-year life expectancy of Gen X, Gen Z is predicted to have a life expectancy of over 100 years.
Scientists have found a way to lengthen worms' lives so much, if the process works in humans, we might all soon be living for 500 years. They've discovered a "double mutant" technique, when applied to nematode worms, makes them live five times longer than usual.
In Sanatan Dharma, Mahabali, Ashwatthama, Ved Vyas, Hanuman, Vibhishana, Kripacharya, Parshuram, and Markandeya are the eight immortals known as Astha Chiranjeevis. They have lived from one Satyug to another. They still exists on earth, and will remain alive until the next Satya Yuga.
The Seven Immortals of Indian Mythology aspires to stir our emotions and help us derive lessons from the life of the Seven Immortals - Ashwatthama, Mahabali, Ved Vyasa, Hanumana, Vibhishana, Kripacharya and Parshurama. They are also known as Chiranjeevis or extremely long lived persons.
