Document Summary

Fatherhood is associated with reduced t and lower aggression in order to protect the child. Dictates that male t increases when they are watching sporting events where their team is winning. Aging in a biological process, not a disease, characterized by lower immunity, decreases muscle mass, reduced tissue and physiological functions, and cognitive declines. Nutrition and diet, physical and physiological stress, smoking, sun exposure. Aging and death is pre-programmed by the body. This is seen in how telomere caps get shorter and shorter with age, leading to an increase in un-repaired damage. Senescent cells gather at sites related to pathologies and increase in number with age. Senescent cells can be caused by epigenetic damage, oncogenic mutations, metabolic imbalances, and organelle stress. Senescence-associated secretory phenotype (sasp) responsible for growth arrest, secretory phenotype, and resistance to apoptosis. Senesce, however, can be a good thing, as senescent cells act as tumor suppressors so taking them away could lead to cancer.
