How does the lifespan of a massive star compare to the Sun's expected lifespan?

Answer

Significantly shorter, perhaps only a few million years

Massive stars burn through their nuclear fuel much faster due to higher core fusion rates demanded by extreme gravity, resulting in lifespans measured in a few million years compared to the Sun's expected ten billion years.
