If it takes you more than 15 minutes to walk a mile, something is seriously wrong. Until a local plant closed down, my neighbors regularly walked to and from work, about four miles away and worked 10-12 hour shifts.
I'm old and even waking my pet and stopping so they can do their business a few times only takes about 15 minutes, 20 if they're being extra leisurely. This is just daily life for most of us, except the drug dealers and their stables.
