aram saroyan
the longest living person whose dates of birth and death were verified according to the modern norms of "guinness world records" and the gerontology research group was jeanne calment (1875–1997), a french woman who reportedly lived to 122. reduction of infant mortality has accounted for most of the increased average life span longevity, but since the 1960s mortality rates among those over 80 years have decreased by about 1.5% per year. "the progress being made in lengthening lifespans and postponing senescence is entirely due to medical and public-health efforts, rising standards of living, better education, healthier nutrition and more salubrious lifestyles." animal studies suggest that further lengthening of median human lifespan as well as maximum lifespan could be achieved through "calorie restriction mimetic" drugs or by directly reducing food consumption. although calorie restriction has not been proven to extend the maximum human life span, as of 2014, results in ongoing primate studies have demonstrated that the assumptions derived from rodents are valid in primates as well [reference: nature 1 april 2014].

tortoises are unique among vertebrates in that the pectoral and pelvic girdles are inside the ribcage rather than outside. tortoises can vary in dimension from a few centimeters to two meters. they are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. they are generally reclusive animals. tortoises are the longest living land animal in the world, although the longest living species of tortoise is a matter of debate. galápagos tortoises are noted to live over 150 years, but an aldabra giant tortoise named adwaita may have been the longest living at an estimated 255 years. in general, most tortoise species can live 80–150 years.
