Science has definitely proven that sitting is murdering you, which is bad news for a workforce that spends 65% of its waking day planted in an office chair. (Note: We researched that figure while planted in an office chair, because irony is real.)

The more you're sedentary and clackity-clacking away on your computer machine at an office, coffee shop, couch, or airport terminal, the quicker your body is losing its lifelong battle with gravity. Alan Hedge is director of the Human Factors and Ergonomics Research Laboratory at Cornell University, so he's basically the sitting expert on sitting, and his prophecies are not real encouraging. "Poor seating leads to lower-back pain, injury to the lumbar discs, poor circulation to the legs, and deep vein thrombosis," he says darkly. Poor posture, on the other hand, leads to all of the above plus pain in the neck and shoulder, cubital tunnel syndrome in the elbow, and our old friend carpal tunnel: gradual mechanical breakdown, basically, while you're drafting fantasy QBs.

Yet since at least half of us aren't presidential candidates, most of our days aren't terrifically active. And that means we have two problems to address:

Problem A: "How can I sit less?"

Solution: Get up and walk around every half hour. Luckily, the Internet has left you unable to concentrate for anything more than 30 minutes anyway.

Problem B: "Okay, but for the times when I pretty much have to be sitting, because I am obviously not cranking on Microsoft Excel whilst standing up, how can I improve my situation?"

Solution: Take the following three steps.

1. Stop scoffing. We'll see who's laughing when you're 60 and your torso can't swivel. Look around this website and you'll see a lot of swanky fall boots, movie gods in broody dark suits, and Instagram models in Barbados. We recognize that your work chair is not the coolest thing you'll consider this week. But you're seated in this object for eight to ten hours every weekday, which is probably more than you're wearing broody dark suits or snorkeling with Charlotte McKinney. Don't blow this off.

2. Buy a new chair. Better yet, make your company buy you one. Hedge sees guys making the same mistakes when buying or choosing office chairs. "They buy based on looks, price, or a two-minute butt test," he says. Hedge says those butt tests need to be much longer, and that testing an ergonomically correct chair in a showroom is akin to test-driving a car for 30 feet. "A beanbag is comfortable for the first few minutes, too," he says. "But then..."

3. Straighten up. Once you have your fancy new chair, don't blow it by slouching. Instead, make sure:

A) Your feet are comfortably planted on the ground.

B) Your screen is at arm's length.

C) Your screen is at eye level.

D) Your back is supported. If you need to, tuck a cushion between your lower back and the chair. Yes, your grandma did this. That's why she lived so long.
