Hell, I had high levels of vigorous physical activity and had the cardiovascular fitness of an athlete and still had a stroke. Good conscience laundering but not really that helpful. I'll live some 40 years past my stroke which means I'll have lived with cardivascular disease 4/9s of my life(44%).

Abstract
- Background: Quantifying the associations of
moderate to vigorous intensity physical activity (MVPA) with years lived
free of cardiovascular disease (CVD) allows for contextualization of
the population burden and provides a metric for clinician-patient
communication. We hypothesized that individuals with lower levels of
MVPA during middle age will have fewer years lived free of CVD compared
to those with higher levels.
Methods: A standardized z-score for MVPA was created based on participant-reported physical activity in 28,466 middle aged adults aged 40-59 years (43.6% women) in 6 U.S. prospective cohort studies. Z-scores were then categorized into quartiles for each cohort. Rates (person-years) of incident CVD and death were summed for participants up to age 95 years, or to the oldest age of observation. Irwin’s restricted mean was used to calculate years lived free from CVD and overall survival stratified by sex.
Results: Over 514,324 person-years of follow-up, 3,556 CVD events were observed. Whereas there was no difference in survival time among participants in the upper 3 quartiles, women in the lowest quartile vs. the next lowest quartile lived 3.2 fewer years and men lived 1.2 fewer years free of CVD. Survival after a CVD event was lower for women in the lowest MVPA quartile (mean±S.E: 0.07±0.32 years) compared to all other quartiles (Q2: 0.67±0.16 years to Q4: 0.96±0.16 years). Survival after CVD events was similar across all quartiles of MVPA for men, ranging from 1.1±0.05 to 1.4±0.05 years.
Conclusions: The benefits of physical activity extend multiple decades into older ages. Even modest levels of physical activity during middle age is associated with longer CVD-free survival, particularly among women.
