Questions & Answers

Q: What is the primary goal of the field of geroscience?

The field of geroscience aims to understand the process of aging and develop interventions that can slow down aging and prevent age-related diseases. The goal is to extend the health span of individuals.

Q: How are recent advancements in geroscience changing the way we think about health?

Recent advancements have shifted the focus from merely describing the aging process to actively developing interventions. The goal is to improve health and delay the onset of age-related diseases, rather than just extending lifespan.

Q: What are some of the promising findings in geroscience research?

Promising findings include the discovery that components of young blood can reverse aging phenotypes in old animals, the potential benefits of targeting senescent cells, and the identification of biomarkers that can measure biological age and predict the rate of aging.

Q: How do companies and startups in this field navigate the challenges of regulation and approval?

Startups in the longevity field face challenges in terms of regulatory approval and choosing the right disease indication for their therapies. They need to prove safety and efficacy and navigate the changing mindset of regulatory agencies.

Summary & Key Takeaways

• The podcast explores the distinction between life extension (achieving immortality) and health span extension (promoting longer, healthier lives).

• The field of geroscience aims to translate findings from lifespan extension research in model organisms to improve the health of humans.

• Recent advancements include identifying biomarkers for aging, exploring the role of blood factors in aging, and targeting senescent cells to slow down the aging process.
