The Oxford Longevity Project published a report titled "Living Longer, Better," stating that individuals are responsible for at least 80% of their health in old age. The report indicates that personal control over lifespan is far greater than commonly perceived. The conclusions of the report are based on multiple studies, which suggest that at least 75% of human lifespan is determined by environmental factors and modifiable lifestyle factors. One study used data from nearly 500,000 participants in the UK Biobank. The results showed that environmental exposure and habits have a far greater impact on premature death and biological aging than genetic factors. The report advises avoiding processed foods, completely abstaining from alcohol, ensuring adequate sleep, and not eating after 6:30 PM, cultivating what is termed a "non-meat mindset." On the issue of alcohol, the report is more blunt, stating that alcohol is toxic and should not be consumed. Critics argue that the report's conclusions are overly simplified, as individuals have limited control over their choices in issues such as poverty, pollution, and healthcare.
