Super Centenarians

Cellular Clock Theory
Cells can divide a max of around 75-80 times, so age makes cells less capable of dividing
Telomeres
DNA sequences that cap chromosomes will become shorter
Lifespan
Oldest possible age members of a species can obtain
-120 to 125
Longevity
Genes seem to bestow an inherent maximum lifespan
Lifespan Average
The age assigned at birth in which people born in the same year will be half alive still and half dead
-indicates the number of years a newborn would live if mortality rates stay the same throughout their life
Lifespan Average Indicates
The number of years a newborn would live if mortality rates stay the same throughout their life

Women live longer than men
-Except in cultures where women are treated worse than men (often countries with less healthcare)
Signs of biological aging
- Vision: only 10% of late adults can see well without glasses
- Hearing: By 90, most men and half of women are fully deaf

Osteoperosis
Cells that reabsorb bone outnumber cells that build bone
