Many people suffer pain from too much sitting. Esther Gokhale, an acupuncturist has researched human spine shape. She says we have forgotten how to use our bodies. Some people slump over too much, So they have C shape spine, and others pull their necks forward while their back and butts are pulled back. Both shapes are unnatural and a recipe for body injuries. Ester started her research after having back pain as a young mother. She did some surgery, but it did not work out. She read medical studies and found that traditional cultures don't have this problem, So she decided to study them firsthand. she found that despite having demanding lives these people are pain-free, and it is because of their spine shape which is straight from the top and curves at the bottom.
