Longevity Revolution: No more tired aging!

Longevity refers to the science of age-related functional decline and the search for strategies to extend both lifespan and health-related lifespan. Research focuses on molecular mechanisms of aging as well as practical measures that can be implemented in everyday life. With increasing age, the efficiency of energy production in mitochondria decreases, promoting cellular stress and oxidative damage.

Genetic and environmental factors

Genetic influences (~20–30%)
Twin and family studies show that genetic predisposition determines an estimated 20 to 30 percent of lifespan. Genes responsible for this include those that regulate cell repair, inflammatory responses, and oxidative stress.

Environmental and lifestyle factors (~70–80%)
Approximately 70 to 80 percent of age-related variation is explained by environmental conditions, diet, exercise, and psychosocial factors. These external influences modulate cellular metabolism and can inhibit or promote age-related diseases.

Inflammatory processes (“Inflammaging”)
Chronically elevated inflammatory markers are associated with many age-related diseases. A delicate balance between immune activity and regulation is crucial for healthy years.

Molecular basis of aging

Telomere shortening
Telomeres are protective caps at the ends of chromosomes. They shorten with each cell division and eventually trigger cell aging.

Cellular senescence
Old or damaged cells continue to grow, but release inflammatory factors and affect neighboring cells.

Mitochondrial dysfunction
With increasing age, the efficiency of energy production in mitochondria decreases, promoting cell stress and oxidative damage.

Longevity therapies

• Approved therapies : Metformin and Rapamycin/Draag are primarily used in studies; no general "anti-aging approval" has yet been granted.
  
• Dietary supplements : NAD boosters are safe, but their long-term effectiveness on aging processes is still unproven.
  
• Senolytics : Initial human studies show safety and localized effects; larger studies are still pending.
  
• Gene therapy & telomerase : exciting research, but currently only preclinical.

Until high-tech interventions are widely available, the medical standard remains prevention and a healthy lifestyle . Those specifically interested in off-label therapies should seek advice from specialized gerontology clinics.
