If you're lucky enough to live to the age of 82 and each day of your existence was represented by a single drop of water, this here bottle is your life.

A drop of water conveniently measures in at .05 mL and makes for quick work:

.05 mL x 365 days/year x 82 years = 1,496 mL (or 1.496 L)

The exact capacity for a 1.5 liter bottle of water—1,500 ml—is 82 years and 8 days.

Drink up.
