There's been a lot of research over the past couple of years about the life-shortening effects of sitting. Your chair really is trying to kill you, the more you sit the earlier you will die.
It might be best to avoid a stylishly comfortable Aeron chair and choose the most uncomfortable chair you can find so as to discourage prolonged sitting.
Part of the problem could be in the way we sit, our posture, and the posture we are taught from an early age to assume: straight back, shoulders back, etc, isn't a natural form.
Slumping, if it's done right, alleviates a lot of tension and allows the spinal column to do its job: redistribute stress and support the body's organs to do the things they need to do.
Esther Gokhale, founder of the Esther Gokhale Wellness Center in Palo Alto, in the video above, shows how to assume a more natural "primal" posture. (Just published on Stanford University's video channel.)
An Australian study of 8,800 people over a six year period found that for each hour spent sitting increased the risk of death from heart disease by one-fifth.
Is it because of a sedentary lifestyle? No.
A study that tracked more than 17,000 Canadians for more than 12 years found people who sat more had a higher death risk, independently of whether or not they exercised.
So maybe it is how you sit.

Esther Gokhale … has pursued hundreds, even thousands of people around the world, mimicking their body alignment and walking style until her shadow matched theirs.
