8 Key Concepts
Healthspan
Healthspan refers to the number of years a person lives in good health, free from chronic disease and functional impairment. It is distinct from lifespan, which is merely the total number of years lived, often including years with poor health.
Wellderly Project
A research initiative that assembled 1,400 individuals, averaging in their late 80s, who had never been sick, were on no medications, and had no age-related conditions. The project aimed to find genetic underpinnings of healthy aging but surprisingly found genetics played a minor role, suggesting lifestyle and immune system health are more significant.
Lifestyle Plus
An expanded definition of healthy lifestyle that goes beyond traditional factors like diet, exercise, and sleep. It incorporates environmental conditions (e.g., exposure to toxins, air pollution, microplastics, forever chemicals), socioeconomic status, loneliness, social isolation, and emotional outlook, emphasizing personalized nuance within these areas.
Big Three Diseases
These are the three major age-related chronic diseases—cardiovascular disease, cancer, and neurodegeneration (e.g., Alzheimer's, Parkinson's)—that collectively account for 85% of healthspan compromise. They share commonalities such as long incubation periods (20+ years) and involvement of the immune system and inflammation.
Polygenic Risk Score
A genetic score derived from analyzing a million or more genetic markers in an individual's genome that are linked to common diseases. It provides a readout of a person's risk for conditions like cancer, Alzheimer's, and heart disease, serving as a guide for personalized prevention efforts.
Organ Clocks
A concept involving the measurement of up to 11,000 proteins from a blood sample to determine the pace of aging for individual organs (e.g., brain, immune system, heart, liver) and the body as a whole (via a methylation clock). This allows for early detection of organ dysfunction and personalized health monitoring.
P-tau 217
A specific biomarker, a modified tau protein at residue 217, that can be detected in the blood and serves as an important marker for Alzheimer's disease risk. It can help identify high-risk individuals 20 years before symptoms, and its levels are modifiable through lifestyle interventions like exercise.
Precautionary Principle
The idea that when there is sufficient evidence to suggest potential harm from certain exposures (e.g., plastics or forever chemicals), even without definitive causative proof, it is prudent to adopt a cautious approach and take action to reduce exposure.
17 Questions Answered
Key factors include lack of exercise, obesity, poor diets (especially ultra-processed foods), poor sleep health, and environmental exposures like air pollution, plastic burden, and forever chemicals.
Focusing on healthspan means living longer with good health and functionality, rather than merely extending life with poor health, frailty, or dementia, which often characterizes the gap between average healthspan and lifespan.
The project found that genetics accounted for very little of why some people live to 85+ without chronic diseases, suggesting that other factors like lifestyle and a healthy immune system play a much larger role.
It broadens the definition to include environmental conditions (toxins, air pollution, microplastics, forever chemicals), socioeconomic status, loneliness, social isolation, emotional outlook, and emphasizes personalized nuances in diet and exercise.
These 'big three' diseases typically take around 20 years or more to incubate in the body before the first signs and symptoms become apparent, offering a significant window for preventative action.
Poor diet is linked to 22% of all deaths, according to multiple sources including global burden of disease studies.
No, there is no one diet that is right for all people; individual responses vary based on metabolism, epigenomics, gut microbiome, and other unique factors.
Exercise has the biggest impact, profoundly affecting all three age-related diseases, slowing biological aging, and maintaining a high-integrity, anti-inflammatory immune system.
Good posture and balance training are crucial as we age because proprioception is compromised, increasing the risk of falls and musculoskeletal injuries. Training these can help maintain a younger level of function.
Observations from the Wellderly Project and other research suggest a strong correlation between an upbeat, hopeful disposition and healthy aging, though the exact mechanism is not fully understood.
Forever chemicals (PFAS, perfluorocarbons) are non-degradable chemicals found ubiquitously in our environment (furniture, tires, personal care products, non-stick pans). They are pro-inflammatory, noxious to health, and accumulate in the body, posing a significant health burden.
When individuals receive their specific health data, such as a high polygenic risk score for heart disease or elevated BPA levels, it significantly increases their likelihood of making durable and important lifestyle changes.
A polygenic risk score assesses an individual's genetic risk for common diseases like cancer, Alzheimer's, and heart disease by analyzing millions of genetic markers. It serves as a guide for risk, allowing for early vigilance and targeted prevention strategies.
It is recommended primarily for individuals with other features of increased risk, such as having the APOE4 allele, a family history of Alzheimer's, or a high polygenic risk score.
No, it's never too late; studies show that even starting at age 50 can add at least seven years of healthy aging, and starting younger yields even greater benefits.
Yes, social isolation and lack of connection are significant factors across all three age-related diseases, and being engaged with others is vital for health.
It should be looked at, as it could be indicative of vascular dysfunction or other underlying health issues like high blood pressure, though it is not always indexed to the vascular tree.
