Live Long, Die Short: The case for compression of morbidity

Interview with Dr Roger Landry, a preventative medicine physician and the president of Masterpiece Living, a group that is committed to the vision of people maximizing their potential and aging successfully.

Why do I care about trying to understand the aging process?
  
Specifically, I am sometimes asked, why do I focus so much on living a long life?  I would say, a long, healthy life. The answer, to me, is obvious. 

First, the alternative does not sound like fun. 

Second, the global benefits of having a fit, elderly population are almost immeasurable - both fiscally and practically. A healthy generation of baby boomers would spend less on health care, contribute to society and fulfill personal goals that their parents could only dream of. 

Which brings me to my third reason to live long and healthy.  I have a very long bucket list. I will never run out of things to do.

I am always curious to hear how other, like-minded, aging enthusiasts respond to the same question. When I met Dr Roger Landry recently, he gave me this answer.


"I have many people say, 'I don’t want to live to be 100', but it is under the mistaken presumption that that it will involve a significant decline, impairment, pain, a burden to their families - and yet if I ask them in their 50’s if they’ve had enough life, no one ever answers ‘yes, I’ve had enough life.' 

"We have the capability, to describe it best as an analogy, to live with the performance capabilities that we have say in our 40’s or 50’s or low 60’s for much much longer.  It’s a matter or throwing away potential capital that you have, it’s throwing away money you’ve saved and so it makes no sense to me. 

"Perhaps those who plan societies may say 'what are we going to do with a world population that’s that large' but that’s a little beyond my pay grade.  I’m about the quality of life of those who are living and having them reach their potential and contribute back to society as well as enjoyment of life."

I agree and would add - returning to the bucket list - that I aspire to get to 90 or 100+ and to travel to those countries that I've always wanted to visit because I am still physically able.  Or, for those with children, wouldn't it be wonderful to reach a great age and still be able to crouch down on the floor (probably with your great grandchildren) and play - and then stand up without getting someone to haul you back into the rocking chair. 


Dr Landry has written a fascinating book, Live LongDie Short: A Guide for Authentic Health and Successful Aging. A The book's title is inspired by a public health term, compression of morbidity, about which I have written in the past.  

As Dr Landry explains: 

"Morbidity is being sick and we like to compress the time that someone is sick rather than to have a long decade, two decade, three decade-long period of decline that is not only detracts from the quality of life, but is also very expensive as a nation, as well as an individual."

Listen to the full interview:

Dr. Landy was a flight surgeon in the Air Force for over 22 years.  He retired as a highly decorated full Colonel and Chief flight surgeon at the air force surgeon general’s office in Washington DC after duty on five continents. He was medically involved in a number of significant world events including: Vietnam, the Chernobyl nuclear disaster, the Beirut bombing of the Marine barracks, the first seven shuttle launches, and the first manned balloon crossing of the pacific.

BBC Presents: What If We Could Stay Young Forever?

Today I'll be presenting a SXSW version of the BBC documentary, What if we could stay young Forever. If you're in town for the interactive conference, I'd love you to come along, if you can. I'm also curious to know how much you care about the aging process and whether you think companies like Google, through their new startup, Calico, can do anything to extend the human life span?

SXSW: "BBC's Peter Bowes will tell the story of his 2-year quest for a healthier, longer life. While walking at a modified treadmill podium, to make a not-so-subtle point about how sitting is killing us, Peter will relay his experiences as the subject of a clinical trial, testing an extreme diet intervention.  Intrigued by the growing business of life extension and bombarded with adverts promising a longer, healthier life, Peter set out to sort facts from fiction in the world of human longevity. He met the 74 year old Las Vegas doctor, appropriately named Dr Life, who injects himself with testosterone to maintain the physique of a man half his age. He discovered the extreme dieters, who practice caloric restriction as a way to slow down the body clock. He tried intense exercise and even enrolled in a university clinical trial as human guinea pig. The study is testing a theory that may help people grow old without ever suffering from the debilitating diseases that plague the elderly."

A high protein diet could lead to early death, claim researchers

(Thierry de Lestrade) Salvatore Caruso, 108 
Too much protein during mid-life - especially protein derived from animal sources - could lead to an early death, according to US and Italian researchers.  In a paper, co-authored by Dr Valter Longo, at the USC's Longevity Institute, it is argued that people who eat a diet high in animal proteins during middle age are four times more likely to die of cancer than those on low-protein diets.  Statistically - and if accurate - this can be compared with the death rate from smoking. The study also concludes that for people over 65, a diet higher in protein could be beneficial. 

This is a fascinating study based on a large sample of adults tracked during nearly two decades. The data is compelling but additional research is needed to further understand the biological mechanisms at work.  The researchers have been criticized for comparing smoking deaths with those (potentially) from eating high protein diets.

According to the Guardian newspaper:  "Gunter Kuhnle, a food nutrition scientist at Reading University, said it was wrong "and potentially even dangerous" to compare the effects of smoking with the effect of meat and cheese as the study does."

High-protein diets: Bad for the middle-aged, good for the elderly

Photo: Like others in the small town of Molochio, with one of the highest prevalence of centenarians in the world, Salvatore maintained a low-protein, plant-based diet for the majority of his life, but switched to a higher-protein diet after moving in with his son's family once he became frail.

Note: Dr Longo (cited above) devised the periodic fasting program that I am experimenting with this year.  I am intrigued - but not necessarily convinced - by the low/zero animal protein argument.  But after two months on a Vegan diet, I feel good and my weight management issues have all but disappeared. I will be fasting again soon for five days.
