One of modern society’s greatest achievements is the dramatic rise in the average global life expectancy. A baby born in the early 1900’s could not expect to live much beyond 50 years old, but people in many countries now live well into their 80’s and 90’s. As a consequence of this rapid change in our society, we have seen a major shift in the leading causes of death, with a corresponding increase in chronic diseases such as cancer, obesity, diabetes, and Alzheimer’s disease.

However, most of us not only want to have a long lifespan, but also a long healthspan; to be fit and healthy throughout the course of our lives. As we move into this unprecedented era of human history, a question arises: how far can the human healthspan be extended, and what are the most effective ways to achieve longevity?

In September 2017, the Icelandic Health Symposium is bringing together some of the world’s best experts in health and longevity to help you discover:

  • What science has to say about the importance of lifestyle on our health and lifespan.
  • The extent to which our genes control our fate.
  • How to optimize our physical performance for longevity.

Lastly, but maybe even more importantly, you will learn how our species can achieve longevity in a way that harmonizes with nature, so both humans and our planet can have a long, sustainable future.

What better place to learn about the best ways to optimize your own health and longevity than Iceland? Home to some of the strongest and healthiest humans on the planet!

Doug McGuff, MD became interested in exercise at an early age when he first read Arthur Jones’ Nautilus Training Bulletin No. 2. His interest in exercise and biology led him into a career in medicine.

In 1989, he graduated from the University of Texas Medical School at San Antonio and went on to train in Emergency Medicine at the University of Arkansas for Medical Sciences at Little Rock where he served as Chief Resident. From there, Dr. McGuff served as Faculty in the Wright State University Emergency Medicine Residency and was a staff Emergency Physician at Wright-Patterson AFB Hospital.

In 1995, Dr. McGuff moved to Seneca, South Carolina where he joined Blue Ridge Emergency Physicians with whom he continues to practice full-time emergency medicine.

Throughout his career Dr. McGuff maintained his interest in high intensity exercise. Doug realized a lifelong dream when he opened Ultimate Exercise in November, 1997, where he and his instructors continue to explore the limits of exercise through their personal training of clients.

In addition to his work at Ultimate Exercise, Dr. McGuff is a full-time practicing emergency physician who lives in Seneca, South Carolina with his wife of 30 years, Wendy, and their children Eric and Madeline.


Dr Chatterjee, 38, is the star of the new BBC One series Doctor in The House, which sees the GP live with three different families in their own homes for a month at a time. He scrutinises them at work, at play, shopping for food and cooking, eating and sleeping.

After qualifying from Edinburgh University Medical School in 2001, Dr Chatterjee spent his first six years in hospital medicine. He completed his internal medicine examinations gaining Membership of the Royal College of Physicians.

However, He soon realised that his passion was in connecting with people and building relationships, so he made the decision to move to General Practice. He didn’t want to spend his whole career seeing problems in one single specialty. To him, the whole body is connected and so it was a natural decision for him to move to General Practice.

Within a few years, it became clear to him that he was only really helping about 20% of the patients that were coming in to see him. So he began searching for solutions.

He soon became aware of where the gaps in his training were. For acute problems such as trauma, infections or catastrophic events like heart attacks, the medical training from Edinburgh University Medical School was superb.

However, for the majority of problems seen on a day to day basis – headaches, joint pain, gut problems, indigestion, weight gain, stress, diabetes and skin problems – He realised that the training was lacking in certain areas.

There was a key turning point Dr Chatterjee‘s life when his son was six months old. He nearly died from a preventable vitamin deficiency. Modern medicine saved his life but taught him nothing in terms of how to prevent the long-term complications from his condition.

Dr Chatterjee immersed himself in nutritional science and came across new research that was not being utilised in conventional medical care. In his mind doctors are practising a type of medicine suitable for acute care but not as relevant for the new epidemic of chronic lifestyle-driven conditions.

Since then, Dr Chatterjee has studied Movement Science, Stress Reduction, Ancestral Health, Nutrition and Functional Medicine. He has also completed a BSc Honours Degree in Immunology. This has proven invaluable in navigating the exciting new field of mucosal health and the gut microbiome.

Dr Chatterjee currently work as an NHS GP in Oldham where he looks after a deprived and socially isolated patient population. Dr Chatterjee also works privately one day per week where he sees patients for 60–90 minutes so that he can delve deeper into what is causing their problem. When he sees patients today, he uses a hybrid approach, integrating all of his experience and research from these different areas. He also draws from his personal experience both as a father and caring for his own father who was ill for 15 years.

Every patient is unique. I advocate for personalised medicine specific to the individual. However, I believe lifestyle and nutrition are always the bedrock upon which all chronic medical management should be founded.
