what it claims

Tennis is the premier physical activity for optimizing longevity because it combines four fundamental pillars of well-being: dynamic interval effort for cardiovascular health, strengthening of muscle mass and bone density, constant mental stimulation, and strong social connection.

The idea that tennis is an exceptional ally for longevity is based on serious scientific foundations, notably the famous long-term observational study Copenhagen City Heart Study (published in 2018). This work highlighted an impressive association between regular tennis practice and a potential gain of nearly 10 years of active life compared to a sedentary lifestyle. The creator's observations are very relevant: tennis engages the body comprehensively by alternating phases of intense effort, strengthening the skeleton, and stimulating mental agility through rapid decision-making. Furthermore, the Danish researchers emphasize that the social dimension inherent in racket sports, which fosters moments of sharing and community, plays a major protective role in general well-being. However, stating absolutely that a sport "adds 10 years" remains a simplified interpretation. As it is an observational study and not a controlled clinical trial, there is an obvious profile bias: regular tennis players often have, on average, a higher standard of living, a balanced diet, and easier access to healthy lifestyle habits, which positively influences these statistics.

What the graded evidence says

Evidence
C

Linked to, not proven to cause.

Effect
difference in life expectancy by leisure sport vs sedentary reference (observational) — adjusted gains vs sedentary: tennis ~9.7 yr, badminton ~6.2 yr, soccer ~4.7 yr, cycling ~3.7 yr, running ~3.2 yr; single cohort, associational
Measured on
adults in the Copenhagen City Heart Study (single Danish cohort, ~8,500 people)

What’s uncertain

These are associations from one observational cohort; healthier or more social people may gravitate to these sports. The specific '~10 years from tennis' figure is the top of the range and shouldn't be read as a causal, individual guarantee.
