Is it really possible to sit for that long everyday and not suffer from it. I know I'm probably focusing on the wrong thing but just the idea of being able to code for that long everyday without suffering any physical problems would be reward enough for me.
It can help a lot of people like me who are struggling to work even 5 hours a day at just 37.
Still thanks for the reply, I am now seriously thinking of getting a standing desk.
<back story> When I was 16 I was a fairly muscle bound half geek / half athlete. To give you an idea, I was a running back on my high school football team, and a tackle and two linemen and I would have to shampoo one anothers head's after weight lifting practice because our arms could not reach the top of our heads from being so buff. We were muscle bound jocks in Iowa, what can I say...
Well, I had a bad tackle when running with the ball during a game, and I crushed 3 vertebra, doubling over backwards with my hips pushed backwards till they touched my shoulders. The stadium had a collective gasp and then silence as I was seen on the field broken. Long story short, bolts in my temples and hanging vertically for 6 weeks healed my young spine with only weather changing aches. However, I went from 230 lbs to 130 lbs, and it took another 6 weeks of therapy before I could walk.
That was the start of a decade of no athletic activity and nihilistic punk rockerism mixed with quite the intellectual journey as I left Iowa and became a part of the Harvard/MIT/BU 3D graphics research community. (This was the early-mid 1980's)
It was not until I was 30 that my then girlfriend, now wife, got me to start morning walks, then light jogs, and finally an actual return to an athletic lifestyle. To give you an idea, at 30 I could not jog a block without heavy panting and sweats. After a year I was able to jog 1 block. It took whole year to do a block without dying! During that year, I'd get delirious and throw up if I pushed. But the persistent and incredible patience of my girlfriend slowly got me back into what is considered "normal" shape.
Once I'd refreshed my previously athletic muscle / body memory, all kinds of positives kicked in like a general optimism, a general active energy level, and greater interest in everything in general.
However, this was tempered with realization that if I slacked for even a few days, I'd get depressed, and if I went a week I'd start having bone/joint chiropractic misalignment and then I'd be injured and unable to be active at all.
So, now I have a strict 3 days (at least) per week hard cardio. I ride my bike about 8 miles, living near a bike path in the San Fernando Valley. Plus I have a yoga mat next to my standing desk. I need to get a newer computer, as a recompile of my work take 10-12 minutes. But I exploit that time working out, so maybe I don't want a new development computer...
