Average global life expectancy is about 73 years — roughly 2.3 billion seconds. In high-income countries it's closer to 2.55 billion. That's the whole budget.
About a third (≈850 million seconds, or 27 years) goes to sleep. Around 320 million go to work. Eating takes ≈110 million. The rest — close to a billion — is the part that actually feels like life.
1,000,000,000 seconds is 31.7 years. See your exact billion-second date on the 1 billion seconds calculator.
