I originally wrote this for my fellow pilots but it applies to all who have jobs where they sit excessively or who otherwise lead sedentary lifestyles:
Most of us of pilots are familiar with the most common health risks associated with long-term sitting such as back strain & pain, disc bulge & herniation, forward-head posture, blood pooling & clotting in our lower legs, constipation, hemorrhoids, and abdominal distention & bloating. But now a recent clinical study published by the American Cancer Society states that long-term sitting even contributes to early-death & colon cancer.
