Not sure how weird it is, but a lot of people tend to let their job keep their butt in a chair for too long. I suggest going into your company's calendaring system (Google or MSFT or whatever) and carving out 30,45, or even 60 minutes. If you're on Google Calendar, call it 'busy' so anyone nosy enough to look at it will think you're meeting with some high-brass and they don't have permission to see details. As far as what to do with the time, doesn't matter as long as your posterior gets out of the chair. Walk, hug your family, or just enjoy the sounds of the outdoors and get sun on your face. I like to do something to get my heart goin for all that time, but frankly there's no need to be fancy. Your idea about oxygen concentration is worth a shot, remember that recirculated indoor air generally has enough CO2 to impact cerebral performance negatively, so going outside will definitely get you some free O2 in addition to making you a lil bit smarter. And for the love of Elvis, don't feel guilty or think of it as time theft. This is your health we're talkin about.
