Your heart is a 3-billion-beat machine

By The Mother LodeMorning Edition4 min read

Also inside: a billion seconds is 31 years, but a million seconds is a long weekend. Big numbers, made touchable.

The Math

Multiply it out. An average heart beats about 70 times a minute, and the minutes are not in short supply:

70 × 60 × 24 × 365.25 × 80 ≈ 2.95 billion

Call it 3 billion beats in a long life — no spares, no reorders. The same arithmetic makes a billion seconds 31.7 years, while a million seconds is just 11.6 days.

Try this — count your beats
