Ever been strapped to your office chair all day - feeling like crap, rundown, unable to focus - and thought, I gotta get outside and get some fresh air? Me too. Everyone does. It's the first thing you learn in science in first grade: We humans need oxygen to survive.

What's not as obvious is what happens when we're not getting enough oxygen. Or good oxygen. It's harder to concentrate, our energy levels go down, and our moods swing like a broken gate. But even stepping outside may not be get us enough good air. Step outside in most cities and you'll get a lung full of car exhaust. Not exactly refreshing. So, besides strapping on one of those oxygen tanks that are all the rage with emphysema patients, how does a guy get some fresh O2 without taking a 'copter to the top of a mountain? A team of athletes, wondering the same thing, came up with the Personal Oxygen Device.

The POD delivers a blast of 95% pure oxygen and 5% nitrogen that can get your body back on track. Great for athletes, pros use oxygen on the sidelines to get them back in the game, it'll energize tired muscles and get your heart pumping. And if you're going to be skiing or hiking in the mountains this winter, a few breaths of highly concentrated oxygen can help your body adjust to the altitudes faster, and keep you out there longer.

For you non athletes: Pure oxygen is great for hangovers. Inhaled deeply, it can help speed those toxins out of your body, and get you up and around faster. (I tried it myself last weekend. Works better than meds.)

The POD carries 40-80 breaths in each can (depending on how deeply you breathe), and is small enough to fit in a pocket or backpack. And it's sleek look means no one will confuse it for an asthma inhaler. Self contained, just place your mouth over the top, twist the cap and inhale, filling your lungs with the good stuff.

And because I know you're all athletes who are gonna hit it hard this winter - and partyers who are gonna hit it harder this tailgate and holiday season - I'm going to give three of you a POD t-shirt and four PODs, so you can experience the benefits of breathing pure oxygen for yourself. Since each POD can last up to a month, depending on how extreme you are, this should take you through a winter of skiing, hiking and drinking. Take a couple to the slopes, leave one in your desk to get you through a rough afternoon at the office and stash one in your night stand, for those mornings after.

All you need to do is drop your email here. And on Friday, I'll draw three of you at random.

And, if you want to give a shot of pure oxygen from POD a shot, they are going to give BG readers a 30% discount off any order from a single POD up to 12 PODs. Just enter the coupon code: BG30 when you checkout. The offer is good until October 31, so get on it.
