Longevity: can ageing be reversed?
- Researchers project that treatments derived from centenarian gene imitation could potentially render a 20-year-old "forever young" within 50 years, though current DNA-level anti-aging drugs remain closer to theory than practical application.
- Significant capital is flowing into Silicon Valley and global startups focused on epigenome modification, driven by the understanding that epigenetic enzymes catalyze reversible reactions, making this a druggable field for slowing aging.
- Current interventions showing promise in extending animal lifespans include parabiosis (blood circulation linking), transplants from young to old organisms, and the modulation of the age-changing gut microbiome.
- Specific drug classes and compounds are under investigation: Senolytics like dasatinib are targeting senescent cells in nearly 20 global clinical trials, Metformin is associated with longer, healthier lifespans and protection against age-related diseases, and Rapamycin is shown to improve cellular function by clearing internal age-related junk.
- Economic and societal expectations include a future where billions live without aging, resulting in a global economic boon, reduced medical expenses due to sharper declines in late-life disease, and increased independence for individuals into their later years, with specific personal goals extending to age 120.
