Is working standing up too expensive? It could cost you as little as $10

Image
Spending too much time sitting down is clearly unnatural, particularly if you sit down on very comfortable chairs . Sitting down per se is probably natural, given the human anatomy, but not sitting down for hours in the same position. Also, comfortable furniture is an apparently benign Neolithic invention, but over several years it may stealthily contributed to the metabolic syndrome and the diseases of civilization. Getting an elevated workstation may be a bit expensive. At work, you may have to go through a bit of a battle with your employer to get it (unless you are " teh boz "), only to find out that having to work standing up all the time is not what you really wanted. That may not be very natural either. So what is one to do? One possible solution is to buy a small foldable plastic table (or chair) like the one on the figure below, which may cost you less than $10, and put it on your work desk. I have been doing this for quite a while now, and it works fine for me. The...

Are you a "Super Souler"?  That's how Oprah affectionately refers to those who watch her Super Soul series on Sunday nights.  Each week she interviews a different thinker, pastor, author, or person who seeks to have a deeper/more meaningful life experience.  She recently had Steven Pressfield on, the author of  The War of Art .  Have you read it?  It was a great conversation about how when we try to go higher or deeper in our lives (be it in our relationships, career, health, parenting, finances, etc.) we will naturally encounter things like resistance, fear, and self-doubt.  But, Steven says, that's when we know we're on the right path.  Two sentences very eloquently written in his book stood out: Whoa.  Is this a lightbulb moment for any of you?  As their conversation continued, Steven shared what I also believe to be true.   Once you commit, and you are on the path to living the life within (the path that resonates with your soul...

Vitamin D production from UV radiation: The effects of total cholesterol and skin pigmentation

Image
Our body naturally produces as much as 10,000 IU of vitamin D based on a few minutes of sun exposure when the sun is high. Getting that much vitamin D from dietary sources is very difficult, even after “fortification”. The above refers to pre-sunburn exposure. Sunburn is not associated with increased vitamin D production; it is associated with skin damage and cancer. Solar ultraviolet (UV) radiation is generally divided into two main types: UVB (wavelength: 280–320 nm) and UVA (320–400 nm). Vitamin D is produced primarily based on UVB radiation. Nevertheless, UVA is much more abundant, amounting to about 90 percent of the sun’s UV radiation. UVA seems to cause the most skin damage, although there is some debate on this. If this is correct, one would expect skin pigmentation to be our body’s defense primarily against UVA radiation, not UVB radiation. If so, one’s ability to produce vitamin D based on UVB should not go down significantly as one’s skin becomes darker. Also, vitamin D ...
