How does a star's mass relate to its life expectancy?

Smaller stars burn less fuel and live longer. A star like ours can exist for more than ten times the size of a star 50 times it's size.
The bigger the star, the stronger it's gravitational pull, and therefore the more intense the nuclear fusion at it's core. Massive stars have a tendency to explode long before they get to be the size of our sun, which has to do with how black holes form, sometimes they collapse back in on themselves.
