Live Long and Master Aging David Walker: Solving a great scientific mystery
Cracking the code behind aging has long since fascinated, frustrated and captivated scientists. In our quest to live longer and better, a desire to fully understand the mechanisms that explain how and why we grow old, has been central to longevity research. In recent years some significant progress has been made. A clearer picture is emerging of the changes that occur, at a cellular level, that could dictate how our bodies respond to the passing years. In this episode of the LLAMA podcast, Prof. David Walker, a researcher at the University of California, Los Angeles, (UCLA) discusses his work with tiny worms and fruit flies, and explains the significance of myriad age-related issues, such as dysfunctional mitochondria, leaky intestines and inflammation.

Topics covered in this interview include:
- Dr. Walker's academic journey from Belfast to Manchester and Los Angeles.
- Inspiration through Jonathan Weiner's Time, Love Memory - a biography of Seymour Benzer, the biologist renowned for his study of genetics through experiments with fruit fly genes.
- Working with nematode worms and fruit flies.
- Aging - a great scientific mystery. How our understanding of what is driving aging, at a cellular level, has evolved.
- Developing novel ways, using genes, to prevent age- related health decline.
- Changing awareness of aging as we grow older.
- Accumulation of dysfunctional mitochondria and how it appears to be an important cellular hallmark of aging.
- The importance of autophagy for maintaining cellular health.
- Why do we age at different rates?
- The pathophysiology of aging: How do age-related changes that affect organ function, relate to the health and viability of the aging organism?
- Leaky intestines in fruit flies and humans .
- Inflammation and the link to age-onset diseases
- Gut bacteria and relevance to various diseases and health interventions.
- Diet and variability of our gut microbiome.
- High/low protein diets and the aging gut, based on fruit fly studies.
- Does eating less protein enhance longevity?
- Making better informed decisions about diet and dietary supplementation.
- Practicing " common sense" lifestyle goals.
- Exercise and everyday diet to counter the effects of aging.
- Memory loss as we age and a better understanding of the mechanisms involved based on studies with fruit flies.
- Lifestyles focussed on living life to the full.
