A Cure for Ageing?: David Sinclair at TEDxSydney

TEDx Talks
15 May 201316:23

Summary

TLDRIn this compelling presentation, the speaker explores the profound challenges of aging, sharing personal stories of loved ones, including his grandmother, to highlight the universal impact of aging. He critiques the limited medical research focused on aging, despite its significant societal and economic consequences. The speaker introduces the concept of 'sirtuins,' longevity genes that can protect against diseases of aging, and discusses exciting advancements in medicine, including resveratrol, that might one day help delay or reverse aging. Ultimately, the speaker advocates for a shift in focus to extend healthy lifespans, emphasizing the responsibility to pursue this science for future generations.

Takeaways

  • 😀 Life is precious and should be embraced, used for good, and valued for health and longevity.
  • 😀 Aging is a universal experience, and it often brings discomfort when we think about its inevitable effects.
  • 😀 The speaker shares a personal moment where his daughter asks if he will always be around to protect her, highlighting the emotional reality of aging.
  • 😀 Aging is a significant issue, and the World Health Organization recognizes it as a problem that could collapse national infrastructures if not addressed.
  • 😀 Despite the awareness of aging’s impact, less than 1% of medical research is focused on understanding why we age or trying to mitigate its effects.
  • 😀 Aging is often ignored or avoided in conversations, with some even labeling the idea of delaying aging as unnatural or controversial.
  • 😀 Aging leads to a disparity in health, where our hearts might remain healthy while other organs, such as the brain, deteriorate, making the overall healthcare system less effective and more expensive.
  • 😀 The solution to aging isn’t just prolonging life, but extending healthy years where the body functions well, avoiding the decline seen in old age.
  • 😀 Scientific efforts to combat aging focus on longevity genes, specifically sirtuins, which have been shown to protect against diseases and potentially prolong life.
  • 😀 Sirtuins, discovered through yeast cells, play a role in how aging affects our genes, and activating these genes could help delay aging and prevent related diseases like cancer and Alzheimer’s.
  • 😀 Resveratrol, a molecule found in red wine, has shown promise in activating sirtuins, though the amount required from wine alone is impractical, driving the search for more potent treatments.
  • 😀 Despite setbacks when major pharmaceutical companies discredited early findings, further research confirmed that molecules like resveratrol do indeed activate sirtuins, promising advancements in age-related medicine.
  • 😀 The speaker envisions a future where we have pills that help delay the aging process and prevent diseases associated with aging, ultimately keeping people healthier for longer.

Q & A

  • What is the main theme of the speaker's talk?

    -The main theme of the talk is the importance of addressing aging and its related diseases, highlighting the need for research into extending healthy human lifespan and preventing aging-related diseases.

  • What personal experience did the speaker share to emphasize the emotional impact of aging?

    -The speaker shared a story about his young daughter asking if he would always be around to protect her. He used this moment to highlight the reality of aging and death, which is something people often try to avoid thinking about.

  • How does the speaker describe the challenge of aging through the example of his grandmother?

    -The speaker describes his grandmother's decline due to aging, particularly her fall and subsequent health complications. This serves as an illustration of how aging can lead to a loss of health and independence, impacting individuals and their families.

  • Why does the speaker believe aging is not given enough attention in research?

    -The speaker believes aging is not adequately addressed in research because society is uncomfortable discussing it. He highlights the fact that only a small fraction of medical research is dedicated to understanding aging, despite its vast impact on society and healthcare systems.

  • What does the speaker say about the perception of aging and its relation to diseases like Alzheimer's or cancer?

    -The speaker challenges the idea that aging is a natural and inevitable process that should be accepted. He compares aging to other diseases like Alzheimer's and cancer, which society actively tries to prevent, even though aging itself is a much more universal issue.

  • What is the key scientific discovery the speaker made regarding aging?

    -The speaker's key discovery is the identification of 'longevity genes' known as sirtuins. These genes have the potential to slow down aging by regulating cellular processes and protecting the body from diseases typically associated with aging.

  • What role do sirtuins play in the aging process, according to the speaker?

    -Sirtuins are proteins that regulate gene activity in cells. They play a crucial role in maintaining the balance of gene activation, which, if disrupted during aging, can lead to diseases. The speaker believes activating sirtuins could delay or even reverse aging processes.

  • What molecule did the speaker and his team discover that could activate sirtuins?

    -The speaker and his team discovered a molecule called resveratrol, which is found in red wine. This molecule has been shown to activate sirtuins, but the speaker mentions that drinking large amounts of red wine is not a practical solution, and more effective drugs need to be developed.

  • What was the setback the speaker faced in his research, and how did it affect his work?

    -The speaker faced a major setback when the world’s largest pharmaceutical company published a paper claiming that resveratrol did not work as previously believed. This caused the speaker's research to be questioned, leading to a temporary halt in clinical trials. However, it motivated him and his team to further investigate the mechanism behind resveratrol and related molecules.

  • What is the ultimate goal the speaker envisions regarding the science of aging?

    -The speaker envisions a future where medicines can be developed to delay or prevent the diseases of aging, potentially allowing people to live healthier lives well into their 90s or even 100s. He believes that this could significantly improve quality of life and reduce the burden on healthcare systems.
