The Bullitt Center is designed to have a 250 year lifespan.

Ostensibly, homes are built with a 50 to 60 year lifespan in mind.

Statistically wind turbines have a 0.001% chance of catching fire once in their 20-25 year lifespans.

It was only produced during the short one year lifespan of the country meaning that all examples are dated 1790.

The development costs for the project are estimated to be between $7 billion - $11 billion over the 20-25 year lifespan of the field.

The plant is short lived with a 3 to 5 year lifespan.

The existing ones were to be phased out after a 40 year lifespan.

The project is worth billions of dollars over its 25 year lifespan.

Over the Forty year lifespan of the project it is planned to plant 25 million trees in the Forest.

Which given a 5-ish year lifespan wouldn't recoup all the money.
