768 days ago - Saving time begins with the keys. My guide for the day, Barron Brooks, has been delivering packages for UPS for the past twenty-seven years, and knows a thing or two about saving time. It takes two seconds to put your keys in your pocket, he tells me, and another three seconds to take them out. For each of the day’s one hundred and sixty stops that adds up to almost an extra fifteen minutes. This is precious time that could be spent getting packages to their destination sooner.
