Life Expectancy

Life Expectancy is the overall amount of life and a part of the vitality each hominid possesses.

Overview
The Life Expectancy of a hominid determines the maximum amount of Stamina it can have, which determines the maximum amount of Energy it can have.

Mechanics
Life Expectancy is depicted on the HUD at the bottom of the screen by the red circle that appears when Stamina is depleted. Seeing the red circle means your hominid is exhausted.

Adult and baby hominids have naturally larger Life Expectancy than elders, which begin with half their life expectancy depleted.

If the hominid is pushed past tired and depletes all of the Stamina, the red Life Expectancy circle will appear and will begin to drain. It is highly recommended to stop moving and wait a moment if the red circle appears. This is trading overall life to perform actions. Only in the most dire situations should this be done! This pulsing red circle indicates that the Hominid is losing overall Life Expectancy, something that cannot be gained back by individuals unless someone in the clan gives birth.

If the hominid stops and rests, some Stamina and Energy will be regained, but the Life Expectancy that was drained will not regenerate.

Food Poisoning,  Venom Poisoning,   Bleeding, and   Injury all reduce Life Expectancy over time. The more times the hominid is injured through these negative status effects, the more that Life Expectancy is reduced.
