Commuting affects your mental health, your physical health, and even the way you think about other people. And these changes are more profound than you might think.
The average commuter spends about an hour a day heading to and from work, but plenty spend as much as three hours commuting. Those hours we spend in the car can have profound psychological and physical impacts on us. A growing body of research shows that there are far more nuanced problems with driving than the ones you’ve probably heard about.
And as a corollary, more scientists are quantifying how “active” commutes, which involve walking, biking, or off-brand hoverboarding can make life better.

The in-house testing lab at the Morgan Hill, California, headquarters of Specialized Bicycle Components is a gleaming example of engineering efficiency: a spacious, well-lit shop where brutish machines rip and wrench bicycle frames and parts to—and past—their limits.
On this particular morning, a special frame sits on the frontal-impact rig. The Venge is an intimidating broadsword of a bike, with a menacing coat of matte-black paint bisected on the down tube by a murderous red slash. A bright white decal spells "McLaren" on the top tube, the logo of Britain’s storied supercar maker and F1 racing team, and Specialized’s longtime technology partner.
The pedal-fatigue test is long and numbingly dull. Test engineers fix the fork to a rigid point on the test jig, and the rear dropouts to an extension that simulates how a frame pivots over the rear tire’s contact patch. The final piece is a dummy drivetrain—including a cassette, chain, and overbuilt crankarms (both oriented at an angle to sustain maximum power transfer). Over the next 14 hours, the test machine alternately slams each crankarm with an excess of 1,200 N of force for 100,000 cycles—essentially a 120-rpm sprint for 14 hours straight. The test is meant to simulate cumulative pedal forces from years of riding.

I have a lot of bikes, and most of them are pretty redundant. They are all mostly for touring and are rusty, olde, hacked, and only work if I ride them. “Oh the front mech won’t work? just kick it a little,” stuff like that. My Atlantis is no exception. I say all the mechanicals and creeks are just reminders that it’s time to stop and have a snack, and/or hang the hammock and take a nap. That being said, it’s still a ripper when it needs to be.
