5 Key Concepts
Epigenetics
These are the dynamic, movable features on our genes that are influenced by environmental factors like diet, exercise, and social engagement. Epigenetics send signals to cells to produce proteins, make energy, and manage toxins, representing the 80% of aging that is within our control.
Metabolic Syndrome
This is a common condition characterized by a mix of central obesity, high blood pressure, early diabetic markers, and abnormal blood lipids. This 'cocktail' significantly increases an individual's risk for cardiovascular events and accelerates the aging process.
Biomarker
A biomarker is a marker of one's biological status, used to identify early physiological changes that may eventually evolve into a recognized disease. Tracking these markers helps understand and potentially intervene in the aging process before disease manifests.
Sarcopenia
This is an age-related disorder involving the infiltration of skeletal muscles, making them less functional. It is much more prevalent than previously thought, particularly in people who don't move much, and is a key underlying factor in frailty.
Chronotype
A chronotype describes an individual's natural inclination for sleep and wake times, coupled with their personality type and 24-hour circadian rhythm. It influences sleep habits, food intake, and energy levels throughout the day, with different types like dolphins, lions, bears, and wolves.
