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...

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...

Evolution of Lactose Tolerance in Africa

Image
Sarah Tishkoff Most African populations have lactose intolerance, but as recently as 3 kya a few pastoral populations have gained the ability to digest milk, which provides evidence of yet another example of ongoing evolution in human population since the time of their origins. Sarah Tishkoff has been studying this phenomenon of recent lactose tolerance in African pastoralist populations. She shared her findings on Sunday morning at #AAASmtg in Washington DC. The ability to digest milk as infants is with the expression of lactase-phlorizine hydrolase (lactase), which is specifically expressed by brushborder cells in the small intestine. But shortly after weaning, the expression of lactase decreases sharply -- that is, except in populations that are lactase persistent. In 2002, an elegant genetic study found the gene for lactase in European populations. Tishkoff showed us in charts and on a map how she performed genetic studies on the African pastoralist populations with lactase to...
