Mental Attitude: Cannabis and IQ?
A recent study indicates that daily cannabis use by teenagers (< 18 years old) results in neuropsychological decline, which persists even after they stop smoking. The group also had IQ scores that were 8 points lower than their counterparts who never smoked or started.

Diet: Chocolate?
Chocolate may be beneficial for reducing stroke risk in men. Flavonoids found in chocolate may decrease blood concentrations of bad cholesterol and reduce blood pressure. Flavonoids, a group of polyphenolic compounds known to have beneficial biochemical and antioxidant effects, appear to protect against cardiovascular disease through antioxidant, anti-clotting and anti-inflammatory properties. Men who ate the largest amounts of chocolate (63 grams - a third cup of chocolate chips - per week) had a 17% lower risk of stroke than men who never, or very rarely, ate chocolate. Also, for each additional 50 grams of chocolate consumed per week (a quarter cup of chocolate chips), there is a fall in stroke risk of about 14%. Many researchers maintain it is dark chocolate that is good for the heart, but about 90% of the chocolate intake in this study was milk chocolate.

Exercise: Lack of Exercise As A Medical Condition?
According to physiologist Michael Joyner, M.D., "physical inactivity is the root cause of many of the common problems that we have." These problems include obesity, diabetes, joint damage, and high blood pressure. If lack of exercise (deconditioning) was treated as a medical condition, then perhaps more patients and doctors would see exercise as a treatment that should be considered first for many medical complaints.

Chiropractic: What Causes Pain?
One possibility is joint pain due to inflammation of tissues between and around the joints. As a person ages, or with trauma (old or new), their joints lose flexibility. As muscles and ligaments tighten and shorten, inflammatory chemicals can become trapped. Over time, the joint complex can degenerate and osteoarthritis may develop.

Wellness/Prevention: TV Time?
31% of US children and adolescents are overweight or obese. Reducing TV viewing may be an effective strategy to preventing excess weight gain among adolescents. In this study, there was a clear association with reduction in TV hours and decreased weight gain over one year.
