A Billion Seconds vs. a Trillion Seconds

The words rhyme, so the sizes feel close. They are not.

• A million seconds is about 11.5 days.
• A billion seconds is about 31.7 years.
• A trillion seconds is about 31,700 years — back past the last Ice Age.

Same jump, applied to money: if you spent $1 every second, clearing a billion dollars takes ~32 years. Clearing a trillion takes longer than recorded history.
