If the estimated age of the cosmos were shortened to seventy-two years, a human life would take about ten seconds. But look at time the other way. Each day is a minor eternity of over 86,000 seconds. During each second, the number of distinct molecular functions going on within the human body is comparable to the number of seconds in the estimated age of the cosmos.

Depending on how we think of them, our lives can be infinitely long or infinitely short.
