[1] The elderly of Okinawa enjoy what may be the longest life expectancy in the world, and are also known for enjoying the relatively good health while doing so. The three leading killers in the West— coronary heart disease , stroke, and cancer—occur in Okinawans with the lowest frequency in the world.
Rather than protecting cells from aging, long telomeres help cells with age-related mutations last longer. [13] This problem prepares the conditions for the occurrence of various types of cancer, and people with longer cell telomeres showed more signs of suffering from types of cancer such as Melanoma and Lymphoma .
The typical normal human fetal cell will divide between 50 and 70 times before experiencing senescence. As the cell divides, the telomeres on the ends of chromosomes shorten. The Hayflick limit is the limit on cell replication imposed by the shortening of telomeres with each division. This end stage is known as cellular senescence.

The US and UK don't even remotely rank close to the top spots.
A mutation in the age−1 gene of the nematode worm Caenorhabditis elegans increased mean life span 65% and maximum life span 110%. [82] However, the degree of lifespan extension in relative terms by both the age-1 and daf-2 mutations is strongly dependent on ambient temperature, with ≈10% extension at 16 °C and 65% extension at 27 °C.
Life expectancy: 79.6 years Massachusetts has the second-longest life expectancy in the country. Only 2.6% of the population is estimated to lack healthcare coverage, and in 2022, the American ...
The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
