It discusses calorie restriction's potential benefits and its limited applicability to wild organisms. Key aging theories involve telomere shortening, DNA damage, and cellular senescence, with implications for cancer risk. Various hallmarks of aging, including mitochondrial dysfunction, genomic instability, and altered cell communication, are highlighted.
