Interesting article in ScienceDaily says that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells. The study gives doctors new clues as to why patients who are bed-ridden often rapidly decline in health. They not only lose muscle mass, but their body chemistry is altered at the cellular level and even their nervous system is adversely impacted.
The study was done on mice, but it doesn’t take much of a leap to see the implications for you and me. I’m sure it’ll spark more study but it seems like a good idea to avoid long periods of inactivity.
According to several sources like CNN/Money, tech stocks have finally recovered from the dot com crash, and it took 17 years. I carried a few tech stocks back then, and they all tanked, so I sold them years ago. I guess I could have waited 17 years. Lesson learned: diversify.
Khan Academy just added an Android app to go along with its existing iOS app. Download from Google Play and check it out. This is the future of learning, where the emphasis is placed on learning and not what the “education establishment” considers “education”. What I mean by that is that “professional educators” all too often are mostly concerned with two things. First, they want to keep the “education club” exclusive, optimizing their wages and job security, but not student success. Second, they emphasize testing as a way to rank students, not as a way to improve learning. There are exceptions of course. Khan Academy is one. For more on this subject, get this book.
Nice chart from USPS showing which method is cheaper. First class for under 7 oz, media mail for greater.
According to Money Magazine, several top tier universities are beginning to offer credits towards a degree through competency-based testing. If you know the material, should it matter if you learned by sitting in a lecture, reading a book, or taking a free online course? The University of Wisconsin seems to be a leader in this progressive thinking, along with U of Mich, U of Texas system, and Purdue. Frankly, I’m a little surprised that these middle-of-the-country bastions of academia are on the forefront of what I think is a great idea. But it shows that the coasts aren’t always leading progress. If more institutions put students first, this would help slow the skyrocketing costs of college degrees.
According to a 11/24 article in the WSJ, 44% of 21-27 year-olds in the US have not tried Budweiser. There was a time that it was the “standard” lager that you either drank or claimed that your beer was better than. Times have changed for the better. So in an attempt to woo the younger crowd, the folks who own Bud will stop or slow down the use of their trademark hay burners.
As a sometimes-sailor, I have to pay homage to the passing of a true hero of sailing, the inventor of the Hobie Cat. Thank you Hobart, for what you gave the surfing and sailing worlds!
