Initially I had returned to school to explore the interface of aerobic exercise and contemplative practices, though my personal interest in joint laxity quickly subsumed my other research questions. While I still hope to explore how aerobic exercise may (or may not) facilitate the recognition of Yoga (Union), I've found that the subject of joint laxity has fully drawn me in. Hyperextended knees are common with joint laxity (Image from bandhayoga.com) As a quick review of past blog postings, joint laxity is a trait that some people are born with. Loose joints are not something that you acquire through yoga practice... joint laxity is distributed via the birth-lottery. Interestingly, the yoga community does seem to be disproportionately populated by people with joint laxity. I'm guessing that this over-representation of hyper mobile people within yoga is based on a self-selection; yoga may be more interesting when loose joints allow you to move more deeply into poses, and

I've long been familiar with the vestibular system, though my depth of understanding was more that of a dilettante than a scientist. In the past week I've been learning about vestibulation in my Systems Neuroscience (Systems) course; and now I have an even greater appreciation of what I did not know that I didn't know (avidya, again!) I used to believe that posture should be perfectly upright. The vestibular system is made up of ten sensing mechanisms - five on each side of your head. Deep within each one of your ears are three semi-circular canals, and two otoliths. The semi-circular canals are sensitive to rotational movements, while the otoliths are sensitive to movements in the front/back and up/down directions. Together, these ten sensing mechanisms provide the information that among many functions; help us maintain upright posture, and keep our eyes focused even when our bodies are in motion. On the first day's lecture, I learned an interesting point abo
