Why do high-mass stars have remarkably short lifetimes compared to smaller stars?

They burn through their fuel supply at an astonishingly high rate.

The furious internal reaction rate in massive stars causes them to consume their greater fuel supply at such a high consumption rate that their active phases are very short, sometimes only tens of millions of years.
