"Exercise or Not, Sitting at a Desk All Day is Bad for You"

“It doesn’t matter if you go running every morning, or you’re a regular at the gym. If you spend most of the rest of the day sitting – in your car, your office chair, on your sofa at home – you are putting yourself at increased risk of obesity, diabetes, heart disease, a variety of cancers and an early death. In other words, irrespective of whether you exercise vigorously, sitting for long periods is bad for you.” http://lifehacker.com/5482856/exercise-or-not-sitting-at-a-desk-all-day-is-bad-for-you

$20 Cintiq Solution (standing allows an ecstatic jig once in a while too)

Update: slip a manual treadmill beneath the stand (such as this $120 version); 
throw away its vertical supports…set it on a lower wooded frame and 
you’re walking while drawing!!  The best ever!!). 

Update: an $800 electric powered seated/standing adjustable desk…for which I cannot envision spending $800, ever.
Update: “Inactivity boosts cancer risk, research finds,” Washington Post: “…among post-menopausal women, taking frequent breaks from sitting was associated with smaller waist circumference and lower risk of some cancers. Even short periods of light activity — frequently standing up and walking for as little as a minute at time — reduced risk for such biomarkers as large waist circumference, elevated triglyceride levels and increased insulin resistance, which are linked to heightened cardiovascular disease but might also boost cancer risk.”
