Ageing is not a genetically programmed process but results from the lifelong accumulation of somatic damage due to evolutionarily optimized, limited investments in maintenance and repair systems.
Focus on maintaining health and minimizing damage (through diet, exercise, and avoiding toxins) rather than seeking a 'genetic fix' for ageing. Your body's repair systems are limited by evolutionary trade-offs, so supporting them with a healthy lifestyle is the most effective strategy for longevity.
