Does genetics play a role in life expectancy?

Post by BoholKing »

The average life expectancy in my father's side is 80, my own grandfather died at the age of 80 and he was a British citizen, also his brothers died at
similar range. Were's on my mum side the average is 95 , most of her uncles reached the age of 95, her own father is currently 85. Does genetics play
a role in the life expectancy of different families? Since obviously health care back home is poor.

Somewhat, it depends on how young your mother gave birth you, the younger she was—the longer you will live. There is something called the 'Hayflick limit'.
The Hayflick limit (or Hayflick phenomenon) is the number of times a normal human cell population will divide until cell division stops. Empirical evidence shows that the telomeres associated with each cell's DNA will get slightly shorter with each new cell division until they shorten to a critical length
Basically, the younger your mother was the longer that cell division will occur because her ability to give birth was better and consequently she produced a longer telomere.

Oh shit I am the second youngest of 8 and not the first born. On a serious note though I think it is something to do with polygamy, most of her uncles and
father practiced it. I need to get myself 4 wives and suck the life out of them. Now I understand why polygamy is allowed in Islam, it has a lot of benefits.



Polygamy is the key to a long life

Want to live a little longer? Get a second wife. New research suggests that men from polygamous cultures outlive those from monogamous ones.

Mostly genetics, although other factors play a role such as the environment, diet, physical activities, stress levels etc, overall good practice of managing your health, goes a long way.
