The Best Explanation of How Running Slower Makes You Faster

Workout Time

Beginning in the seventh grade, I became fascinated with time, how fast it goes and how each year seems to go by faster than the previous year. When I once shared my perception of time with my 90-year-old grandmother, she said, “Just wait until you’re 80.” I’m still far from 80, so I can only […]
