How high can a person count in a lifetime?

Answer 1

Ok, we can work this out! Let's break down how long it would take, on average, to say a number out loud.

1-999 (<= ~1 second) = 999 seconds

1,000-99,999 (<= ~1.5 seconds) = 148,499 seconds

100,000-999,999 (<= ~2 seconds) = 1,799,998 seconds

1,000,000-999,999,999 (<= ~3 seconds) = 2,996,999,997

Total time to count to 1 billion:

2,998,949,493 seconds

OR 49,982,491 minutes

OR 833,041 hours

OR 34,710 days

OR ~95 years.

Considering the average lifespan of a human in a developed country is around 78 years, you'd be lucky to make it to a billion. Cheers!
