Just as today's military elite warfighters continue to use a array of equipment and technology to ensure optimum battlefield performance and safety in a diverse environment, we cannot neglect the importance of an equally diverse and comprehensive approach to the needs of the human being operating in that environment; an approach that is based on strong science in a variety of fields including physiology, psychology, spirituality, sociology, nutrition, and medicine; this ensures we meet a broad range of performance and resilience requirements to ensure maximum force fitness.




Through my work and understanding of the warrior-athlete concept in the US military, I have been fortunate to collaborate with some of the top researchers and performance specialists in the world. This collaboration has provided me with a knowledge base that has led to an important understanding of how specific comprehensive strategies used by the best athletes in the world can be applied to the unique demands of various groups such as aviation and special operations. This demands an appreciation for all influencers of human performance and resilience.

As the likelihood of long duration spaceflight continues to increase as humans want to further their exploration of space and planets, NASA has been researching how to deliver powerful nutrients that can help keep astronauts healthy and performing their best. Astronauts are at increased risk of specific cancers and diseases because of their exposure to larger amounts of damaging radiation and oxidative stress. All of us can apply this data and understanding to our own bodies here on earth for increased wellness.
