Yes? There are plenty (I know at least 7 in my family) people who smoke every day for 80+ years and live without disease before dying their sleep. There are a lot of people who do a lot of sitting and manage to live very short lives.

There might or might not be a health issue with sitting down; for me my personal experience is compelling; I feel YEARS younger since I don't sit more than a few hours a day, relaxing or otherwise. This next to other physical activity. It makes sense to me as well (we didn't used to sit a lot before 1900, so evolution didn't equip our bodies to do so for 8+ hours/day), but that's not really proof/evidence of anything per se, just as 'a lot of people who sit a lot live long' and 'a lot of people who sit a lot die young' are not ;)

I think stress levels are involved too ; sitting cramped / stressed is not very good for you I believe while that is the reality for many 'sitting professionals' ; walking helps reduce stress often so that is a part as well I believe.

Interesting. Thanks for sharing your personal observation. Do you have a standing desk or a new job? For how many years do you sit less now?

[tluyben2]

I have a chair on a table where the sit part of the chair + laptop is exactly the right height for my arms. And I have been doing this for about 2.5 years now. Even wrote a book about it (which I never finished :) I'll revisit it I guess.

Sounds interesting! Can you show a picture maybe?

If I get you right, you use your chair as a desk. That chair is sitting on a normal desk, so combined the height is appropriate for working while standing. Right?

This is my home setup https://dl.dropbox.com/u/6134596/20120530_160149.jpg

When i'm writing stuff I'm usually replacing the laptop by a writing pad.

Thanks. That really is simple (and beautiful)!

I wonder though, isn't it hard for your wrist after a while when you can't rest your lower arm on the desk?

I have a MBP; I rest my wrists on the huge slabs under the keyboard which works absolutely fine. If you computer doesn't have that, then yes, I would make a real table on the table so I can rest my wrists.
