Native camp daily news summary

The biological age of humans is limited to about 120 years.

After the age of 30, the chance of dying doubles about every eight years.

Therefore, getting older causes health problems.

For reptiles, amphibious and fish, there is no sign of aging because of the ability of regenerating their tissue.

On the other hand, mammals were more often hunted by other animals. 

As a result, they don't have to keep their body young.
