Many people experience traumatic events (such as the death of a loved one, witnessing violence, or physical assault) but only a small amount develop Post-Traumatic Stress Disorder (PTSD). A decade long study of 1,000 random residents in southeastern Michigan found those who scored higher on a neuroticism scale (chronic anxiety, depression, and/or a tendency to overreact to everyday challenges and disappointments) were more likely to suffer from PTSD following a traumatic event.

Exercise: Walk Much?
The more moderate physical activity (like brisk walking) you do, the better. Compared to doing nothing at all, seventy five minutes of vigorous walking per week was linked to living an extra 1.8 years. Walking briskly for 450 minutes or more per week was found to provide most people with a 4.5-year longer lifespan. The longer people spent each week being moderately active, the greater their longevity.

Chiropractic: Keep Your Disks Healthy.
In normal healthy disks, the nerves (sinuvertebral) only sense pain on the periphery or outer regions of the disk. In grossly degenerated disks, nerves may penetrate into the center (nucleus) of the disk and be more vulnerable to degeneration and/or inflammation.
Wellness/Prevention: Cell Phone Addiction.
Cell phone and instant messaging addictions are driven by materialism and impulsiveness and can be compared to consumption pathologies like compulsive buying and credit card misuse. Cell phones may be used as part of the conspicuous consumption ritual and may also act as a pacifier for the impulsive tendencies of the user. Impulsiveness plays an important role in both behavioral and substance addictions.
