A part of me is profoundly sedentary. That part of me wants to sit in an easy chair with a book or laptop. Coffee pot, mini-refrigerator, phone, radio, liquor cabinet and other conveniences within reach, so that I only have to get up for biobreaks. I give in to this evil part of me less and less now. I know that it would kill me.

Sitting is Killing You
From: http://www.medicalbillingandcoding.org

Now, most of the data about the ill effects of sitting is correlational, i.e. lots of sitting is correlated with medical problems. That does not necessarily mean that the more you sit, the worse health you have.

Some people respond to the above information by getting a standing desk. If that works for you, fine. But is this a case of more not necessarily being more? We now know that just because getting some aerobic exercise is good for your heart and lungs, it does not follow that you should run five miles per day. Just because lifting some weights has many health benefits, it does not follow that you should spend an hour a day in the gym pumping iron.

Research shows that just getting up frequently to stand, walk around, lift something, stretching, etc. significantly reduces the negative effects of sitting.

Update 9/26/2011: Researchers say getting up and moving every 20 minutes is better than standing. Yeah, right. I make a point of getting up once an hour but I’m not getting up every 20 minutes. Pfft!

My work involves 99% computer time. I have no interest in a standing desk. At my age (68) and given my training, there is no standing job that would keep me much above the poverty level. By doing web design, I can make a very good hourly rate and still have some time to enjoy my semi-retirement.

That’s enough for now. I have to get up and move around.

Ancient Grok ran around outside in a loincloth or nothing all day. Since you probably can’t do that, especially not nakkie, you need to take vitamin D. Forget the conventional wisdom about sun screen and getting enough D by going outside 30 minutes a day in short sleeves. Mark has posted several blogs about sunlight and D. Here is a basic one.

There is an excellent thread in Mark’s Daily Apple. The person who started the thread, Katherine or “Cillakat” as she is called in the forum, has studied vitamin D extensively. She suggests 1000 mg per 25 pound body weight per day in the winter. Less when you are getting lots of sun.

So you think you are getting enough vitamin D and sunshine? Read this post by Dr. Davis. (He has lots of good information but he is not primal or paleo.)

Skeptical? You must read this!

My personal experience –  decrease in colds and flus, and much shorter when I do get them.

Vitamin K – See Mark’s post. However, I take some additional K2 to help the vitamin D3 work properly. I am not convinced that just doing Primal gives me enough K.

This is an old, outdated site. When I made this WordPress site, my attitude was still a pigheaded “I ain’t givin’ up potatoes or tortillas or beans or rice. Fasting? I ain’t fasting when there is good food I could eat.” Etc. I have found that I can cut back on potatoes, white rice, beans and corn tortillas without dying. And I usually fast until around 11 am with no problem. My primary blog is now Ancestral Health Info.
