mortality risk

As humans we have evolved to move, but why are we getting it wrong so often? David Raichlen is the Professor of Human and Evolutionary Biology at the University of Southern California. His research focuses on the connection between human evolution, physical activity, and health, examining why inactivity leads to so many chronic diseases in the modern world. In this conversation David and Steven discuss topics, such as how modern exercise levels compare to hunter-gatherers, the dangers of sitting, how air pollution is linked to dementia, and the misunderstanding of just how much exercise it takes to get health benefits. 00:00 Intro 01:59 My Work: How Lifestyle & Exercise Affects the Brain 03:07 You Can Change an Ageing Brain 05:22 What Is a Neuron? 05:36 What Is the Hippocampus 07:28 The Link Between Exercise and Brain 09:06 What Happens to Our Brain When We Don't Exercise 12:54 People Aren't Meeting the Guidelines for Good Health 15:25 What Activities Are Good for Our Brain? 17:35 Orienteering Can Train the Brain 18:47 How the Different Types of Exercise Increase Neuroplasticity 22:39 Impact of Exercising in Greener Spaces Than Urban 24:06 Better Cognition Exercising Before a Task 25:41 The Optimal Time of the Day to Exercise 27:46 The Hadzas: Researching Hunter-Gatherer Tribes & the Findings 28:56 What Is the Optimal Exercising Time? 31:59 Cardiovascular Illnesses in Hadza Tribe 35:07 What's the Issue with Sitting? 40:29 The Power of Daily Small Amounts of Exercise 42:17 How to Improve Memory 46:08 Top Factors That Fuel Cognitive Problems 48:38 Link Between Human Connection & Brain Impact 50:54 Pollution Impact on the Brain 53:13 Racquet Sports for Brain Health 54:41 How Much Activity Do I Have to Do? 55:52 Endocannabinoid Receptors and Exercise Rewards 57:24 Mental Health Issues Linked to Lack of Exercise 01:01:45 Brain Foods 01:03:07 Reaching Optimal Living 01:07:50 What Causes Alzheimer's? 01:12:39 Last Guest Question Follow David: Twitter - https://bit.ly/483oZIF Watch the episodes on Youtube - https://g2ul0.app.link/3kxINCANKsb My new book!

In this “Ask Me Anything” (AMA) episode, Peter and Bob discuss the longevity benefits from greater cardiorespiratory fitness (CRF) and greater muscle mass and strength. Conversely, they dive deep into the literature showing a rapid increase in morbidity and mortality risk as fitness levels decline with age. They also try to tease out the relative contributions of CRF, muscle mass, and strength. Additionally, they discuss the impact of fasting on muscle mass, the potential tradeoffs to consider, and finish by discussing why it’s critical to maximize your fitness level.

We discuss:

• VO2 max and its association with cardiorespiratory fitness [2:45];
  
• Changing mortality risk based on VO2 max and cardiorespiratory fitness [7:45];
  
• The profound impact of improving cardiorespiratory fitness [15:15];
  
• Muscle mass, function, and loss with aging: how it’s defined, measured, and the cutoff points for sarcopenia [25:00];
  
• Increasing mortality risk associated with declining muscle mass and strength [40:00];
  
• Muscle size vs. strength—which has the bigger impact on mortality risk? [58:00];
  
• Evaluating the cumulative impact of cardiorespiratory fitness and muscular strength on mortality risk when put together [1:03:30];
  
• Investigating the rising incidence in deaths from falls, and what role Alzheimer’s disease might play [1:09:00];
  
• The impact of fasting on muscle mass and the potential tradeoffs to consider [1:14:30];
  
• The critical importance of working to maintain muscle mass and strength as we age [1:20:30]; and
  
• More.

The big short was a fantastic movie, for finance nerds and regular viewers alike. One of the lines that stood out the most, amongst many memorable lines, was the claim that for every 1% increase in unemployment 40,000 people die.   This is an incredibly significant claim, that adds even more weight to the already significant societal issues that come along with people out of the job.  So is this claim actually true?
