How Long Can A Human Live? Debate Reignited After Oldest Person Dies

How Long Can A Human Live? Debate Reignited After Oldest Person Dies


Maria Branyas Morera was born in San Francisco, California, on March 4, 1907.

Paris:

The death of the world’s oldest person at the age of 118 has reignited a debate that has divided scientists for centuries: is there a limit on how long a healthy human can live?

After French nun Lucile Randon died last week, Spanish great-grandmother Maria Branyas Morera, 115, has assumed the title of the oldest living person, according to Guinness World Records.

Back in the 18th century, French naturalist Georges-Louis Leclerc, known as the Comte de Buffon, theorised that a person who had not suffered an accident or illness could live for a theoretical maximum of 100 years.

Since then, medical advancements and improving living conditions have pushed the limit back by a couple of decades.

A new milestone was reached when Frenchwoman Jeanne Calment celebrated her 120th birthday in 1995.

Calment died two years later at the age of 122. She remains the oldest person ever to have lived — that has been verified, at least.

According to the United Nations, there were an estimated 593,000 people aged 100 years or older in 2021, up from 353,000 a decade earlier.

The number of centenarians is expected to more than double over the next decade, according to the Statista data agency.

The Comte de Buffon might also have been surprised by the rise of supercentenarians — people aged 110 or over — whose numbers have been increasing since the 1980s.

Natural limit at 115?

So how far could we go? Scientists disagree, with some maintaining that the lifespan of our species is limited by strict biological constraints.

In 2016, geneticists writing in the journal Nature said there had been no improvement in human longevity since the late 1990s.

Analysing global demographic data, they found that the maximum human lifespan had declined since Calment’s death — even though there were more elderly people in the world.

“They concluded that human lifespan has a natural limit and that longevity is limited to around 115 years,” French demographer Jean-Marie Robine told AFP.

“But this hypothesis is partly disputed by many demographers,” said Mr Robine, a specialist in centenarians at the INSERM medical research institute.

Research in 2018 found that while the rate of death increases with age, it slows down after 85.

Around the age of 107, the rate of death peaks at 50-60 percent every year, the research said.

“Under this theory, if there are 12 people aged 110, six will survive to be 111, three to be 112, and so on,” Mr Robine said.

A numbers game

But the more supercentenarians, the higher chance a few have to live to make it to record ages.

If there are 100 supercentenarians, “50 will live to be 111 years old, 25 to 112,” Mr Robine said.

“Thanks to a ‘volume effect’, there are no longer fixed limits to longevity.”

However, Mr Robine and his team are publishing research this year which will show that the rate of death continues to increase beyond the age of 105, further narrowing the window.

Does this mean there is a hard ceiling on how long we can live? Mr Robine will not go that far.

“We will continue to make discoveries, as we always have, and little by little the health of the oldest people will improve,” he said.

Other experts are also cautious about choosing a side.

“There is no definitive answer for the moment,” said France Mesle, a demographer at the French institute of demographic studies (INED).

“Even if they are increasing, the number of people reaching very old age is still quite small and we still cannot make any significant statistical estimate,” she told AFP.

So it might be a matter of waiting for rising numbers of supercentenarians to test the “volume effect”.

And of course some future medical breakthroughs could soon upend everything we know about death.

Eric Boulanger, a French doctor specialising in the elderly, said that “genetic manipulation” could allow some people to live for 140 or even 150 years.

Gunman Shoots 10 At California Event, Kills Self When Surrounded: 10 Facts

Gunman Shoots 10 At California Event, Kills Self When Surrounded: 10 Facts



Ten people died and at least 10 others were injured in the shooting at a dance club.

Los Angeles:
The manhunt for the suspect in the Los Angeles mass shooting that left 10 dead and at least 10 others injured came to an end after Huu Can Tran, 72, was found dead inside a van. Police say he apparently shot himself after he was surrounded.

Here are the top 10 points from this big story

  1. The 72-year-old yesterday opened fire at a Chinese Lunar New Year party at Monterey Park in California’s Los Angeles. Police tracked him down to a van and surrounded it. As the officers approached the vehicle, they heard a gunshot.

  2. “The suspect sustained a self-inflicted gunshot wound and was pronounced dead at the scene,” Los Angeles County Sheriff Robert Luna said.

  3. The sheriff confirmed that there are no other suspects in the mass shooting incident, and added that the motive for the attack was not yet known. “The investigation is still ongoing,” he said.

  4. Officials have said detectives were reviewing surveillance video and did not yet know whether the suspect was targeting a particular group.

  5. “We don’t know if this is specifically a hate crime defined by law but who walks into a dance hall and guns down 20 people?”, sheriff Luna earlier said.

  6. US President Joe Biden has ordered all US flags at public buildings to be flown at half-staff to honour the victims of the mass shooting, the White House said in a statement.

  7. Tens of thousands of people had gathered for the two-day Lunar New Year festival, one of the largest in southern California. The second day of the festival was cancelled after the attack.

  8. The shooting, the deadliest in the US since a shooter in Texas killed 22 people at an elementary school in May, has yet again brought under the spotlight rising gun violence in the country and easy access to firearms.

  9. The last year saw as many as 647 incidents of mass shooting, with at least four people shot or killed by a shooter, according to the Gun Violence Archive website.

  10. More than 44,000 people died from gunshot wounds in 2022 across the US, more than half of which were suicides.

“Mo-Mo Understanding”: Congress Leader Claims PM Modi-Mamata Banerjee Pact

“Mo-Mo Understanding”: Congress Leader Claims PM Modi-Mamata Banerjee Pact


Congress’s mega foot march started last year in September (File)

New Delhi/Kolkata:

Congress MP Adhir Ranjan Chowdhury today took a jibe at Prime Minister Narendra Modi and West Bengal Chief Minister Mamata Banerjee, claiming they have a pact to weaken Congress.

Adhir Ranjan Chowdhury, who is also the West Bengal Congress Chief, said Mamata Banerjee will not do anything to upset the Prime Minister.

“Several leaders have appreciated Congress MP Rahul Gandhi’s Bharat Jodo Yatra, but not her,” Mr Chowdhury said.

“There’s ‘Mo-Mo’, an understanding between Mamata Banerjee and Modi ji. When Modi ji says- Congress-Mukt Bharat, then Mamata ji also says Congress should be removed from Bengal,” he claimed.

This is not the first time the Congress MP has made such a claim. Earlier, Mr Chowdhury had claimed that there was a “secret understanding” between PM Modi and Ms Banerjee to “save Trinamool Congress leaders” from the central agencies.

“Mamata Banerjee wants to weaken Congress by becoming informer of Prime Minister Narendra Modi. She bowed her head in front of Modi ji to save her party leaders from CBI and ED,” he had said.

Mr Chowdhury had also claimed that BJP’s “polarisation politics” to damage the Congress had helped Mamata Banerjee’s TMC sweep the 2021 Assembly Elections in West Bengal,

With an eye on Lok Sabha elections, Congress started its mega foot march last year in September from Tamil Nadu.

The party has invited 21 opposition parties for the grand finale of the yatra in Jammu and Kashmir on January 30.

Last month, the Prime Minister virtually flagged off the Vande Bharat Express connecting Howrah and New Jalpaiguri in West Bengal, the day his mother died.

Ms Banerjee condoled PM Modi’s mother’s death and thanked him for joining the event in spite of suffering such a huge personal loss.

“Guides, Like A North Star”: Chief Justice On Basic Structure Doctrine

“Guides, Like A North Star”: Chief Justice On Basic Structure Doctrine


Chief Justice made the remarks while delivering the Nani A Palkhivala Memorial Lecture. (File)

New Delhi:

Chief Justice of India DY Chandrachud on Saturday called the basic structure doctrine a North Star that guides and gives certain direction to the interpreters and implementers of the Constitution when the path ahead is convoluted.

The remarks by the CJI came against the backdrop of the recent remarks by Vice President Jagdeep Dhankhar who questioned the landmark 1973 Kesavananda Bharati case verdict that gave the basic structure doctrine. Mr Dhankhar had said the verdict set a bad precedent and if any authority questions Parliament’s power to amend the Constitution, it would be difficult to say “we are a democratic nation”.

Delivering the Nani A Palkhivala Memorial Lecture here, the CJI said craftsmanship of a judge lies in interpreting the text of the Constitution with the changing times while keeping its soul intact.

“The basic structure of our Constitution, like the north star, guides and gives certain direction to the interpreters and implementers of the Constitution when the path ahead is convoluted,” he said.

“The basic structure or the philosophy of our Constitution is premised on the supremacy of the Constitution, rule of law, separation of powers, judicial review, secularism, federalism, freedom and the dignity of the individual and the unity and integrity of the nation.”

The CJI said that from time to time, we require people like Nani Palkhivala, who was an eminent jurist, to hold candles in their steady hands to light the world around us.

“Nani told us that our Constitution has a certain identity which cannot be altered.” He said the doctrine of basic structure has shown that it might be beneficial for a judge to look at how other jurisdictions have dealt with similar problems for them.

The basic structure principle became the ground for setting aside several Constitutional amendments, including the quashing of the Constitutional amendment and the corresponding NJAC Act on the appointment of judges in the higher judiciary.

Mr Dhankhar, who is the Rajya Sabha chairman, recently said he does not subscribe to the Kesavananda Bharati case verdict that Parliament can amend the Constitution but not its basic structure. He had asserted that parliamentary sovereignty and autonomy are quintessential for the survival of democracy and cannot be permitted to be compromised by the executive or judiciary.

Addressing the 83rd All India Presiding Officers Conference in Jaipur on January 11, he said the judiciary cannot intervene in lawmaking.

“In 1973, a wrong precedent (galat parampara) started.

“In 1973, in the Kesavananda Bharati case, the Supreme Court gave the idea of basic structure saying Parliament can amend the Constitution but not its basic structure. With due respect to the judiciary, I cannot subscribe to this,” Mr Dhankhar, who has been a Supreme Court lawyer, said.

Mr Dhankar’s statement came against the backdrop of a raging debate on the issue of appointment to the higher judiciary with the government questioning the current Collegium system and the Supreme Court defending it.

In his lecture, Justice Chandrachud said the identity of the Indian Constitution has evolved through the interaction of Indian citizens with the Constitution, and has been accompanied by judicial interpretation.

“The craftsmanship of a judge lies in interpreting the text of the Constitution with the changing times while keeping its soul intact,” he added.

The CJI also observed that India’s legal landscape has undergone a significant change in the recent decades in favour of removing “strangulating regulations, augmenting consumer welfare and supporting commercial transactions”.

He said the emerging world economy has erased national boundaries, and companies no longer stop at the border.

“In recent decades, India’s legal landscape has also undergone a significant change in favour of removing strangulating regulations, augmenting consumer welfare and supporting commercial transactions.”

The CJI noted that legislations such as the Competition law and the Insolvency and Bankruptcy Code have been enacted to promote fair market competition. Similarly, the Goods and Services Tax (GST) has sought to streamline indirect taxation on the supply of goods and services in India, he added.

“If you look at the Constitution, it does not favour unbounded economic liberalism. Rather, our Constitution seeks to find the right balance.”

The CJI further said the Constitution allows the state to change and evolve its legal and economic policies to meet societal demands.

He said that when individuals have the opportunity to exercise their liberties and to be fairly rewarded for their efforts, then economic justice becomes one of the many inter-related dimensions of life.

Ultimately, we share common faiths and destinies to the point that development of each individual fosters social justice in the entire world, he added.

“We have come a long way from the time when getting a phone required you had to wait for a decade, and buying your car even longer at times. We have come a long way from the time of the control of capital issues,”he added.

Talking about Palkhivala and several prominent cases in which he was involved, the CJI said the eminent jurist was at the forefront of preserving the very identity and cardinal principle embedded in the Constitution.

“Nonetheless, the larger picture of legal culture and local dimensions of law, which are dictated by the local context, should never be obfuscated. Law is always grounded in social realities.”

“Wrestling Chief To Step Aside Till Probe Over”: Minister On #MeToo Charge

“Wrestling Chief To Step Aside Till Probe Over”: Minister On #MeToo Charge

Sports Minister Anurag Thakur met athletes for seven hours

New Delhi:
BJP MP Brij Bhushan Sharan Singh will step aside from India’s wrestling body for four weeks during which an oversight committee will look into allegations of sexual harassment against him, Union Sports Minister Anurag Thakur told reporters today.

Here’s your 10-point cheatsheet to this big story

  1. After a meeting that lasted seven hours and went past midnight, Mr Thakur, flanked by some of India’s most celebrated wrestlers, in a news conference assured that the government will support the wrestlers at every step of their battle.

  2. “An oversight committee will be set up. It will take four weeks to give a report. Any allegation, whether sexual harassment or financial wrongdoing, we will dive deep and investigate them. We will take action after that,” Mr Thakur said.

  3. After meeting Mr Thakur, the wrestlers called off their protest against alleged sexual harassment and misappropriation of funds.

  4. “Till the time the investigation is not complete, a committee will see to the day-to-day working (of the Wrestling Federation of India)…I thank the athletes for speaking to me,” Mr Thakur said.

  5. Olympic medallist Bajrang Punia said the minister has assured he is with the wrestlers at every step. “Prime Minister Narendra Modi has also always supported our athletes,” Mr Punia said.

  6. The Indian Olympic Association has also announced a seven-member panel to investigate the allegations against Mr Singh. The panel will have noted athletes Mary Kom, Dola Banerjee, Alaknanda Ashok, Yogeshwar Dutt and Sahdev Yadav as members.

  7. Mr Singh has denied the allegations and refused to resign. “If I speak, there will be a tsunami…I am not here because of someone’s charity. I have been elected by the people,” he told reporters in Uttar Pradesh’s Gonda.

  8. Earlier, Mr Thakur had dialled Mr Singh and cautioned him against making any statement to the media.

  9. Ahead of the meeting on Friday night, the wrestlers had sent a letter to PT Usha, the head of the Indian Olympic body, seeking action against Mr Singh.

  10. “Vinesh Phogat was mentally harassed and tortured by the WFI chief after she missed out on an Olympic medal in Tokyo. She almost contemplated suicide,” the wrestlers wrote in their letter to Ms Usha, adding “they fear for their lives”. Ms Phogat has agreed to reveal the identity of the sexual harassment survivors to the Indian Olympic Association committee.
