Here's a breakdown:
* Average lifespan: 25 years
* Maximum lifespan: Over 30 years

Factors that influence a grizzly bear's lifespan include:
* Habitat: A healthy, abundant habitat with enough food and safe spaces provides better chances for survival.
* Competition: Competition for resources with other bears or predators can shorten lifespan.
* Disease and injury: Infections, parasites, or injuries can significantly reduce a bear's lifespan.
* Human interaction: Human-caused mortality, such as hunting, habitat loss, and vehicle collisions, can affect population survival.
