Living Longer, Looking Lovely

The document discussed the ongoing search for methods to prevent aging, highlighting caloric restriction as a scientifically valid approach. Studies in mice showed that a 60% caloric restriction from birth nearly doubled their lifespan, but this was not feasible for humans. Dr. Weinrich's research on monkeys demonstrated that a 30% caloric restriction from middle age, supplemented with micronutrients, maintained normal brain mass, renal function, and muscle tone, suggesting that many aging-related conditions might not be inevitable. However, a human experiment in Biosphere II showed that caloric restriction led to negative psychological effects. The document concluded that while caloric restriction might extend life, it does not enhance physical appearance, and modern eating practices need reassessment to address obesity and related health issues. The quest for the "fountain of youth" remained unresolved.
