The hamstrings play a crucial role in many daily activities, such as, walking, running, jumping, and controlling some movement in the trunk. In walking, they are most important as an antagonist to the quadriceps in the deceleration of knee extension Most low back pain and sciatica problems will benefit from a regular routine of hamstring stretching. Tightness in the hamstrings places increased stress on the low back and often aggravates or even causes some of the conditions that lead to low back pain and/or sciatica pain. The hamstrings are a group of three muscles (Biceps Femoris, Semitendinosus & Semimembranosus) located in the back of the thigh. They run from the pelvis down to the knee, and help bend the knee and extend the hip. Because most daily activities including sitting do not stretch the hamstrings, they are often overly tight and specific stretching exercises are needed to keep them healthy and extended.  In addition strenuous exercises often contributes to tight hamstrings. Stretching your hamstrings before and after working out helps alleviate pain and tightness. Back pain sufferers and those with stiff knees will also benefit from a regular stretching routine.

The stomach is the body's food processor.  It takes about 4 hours for a moderate meal to be processed.  It takes 7 seconds for food to travel from your mouth to your stomach.  Your stomach can hold 1.5 litres of food and drink. Chew each mouthful at least 20 times Chewing produces saliva which start the digestive process efficiently, enabling the food to the broken down thoroughly.  Eating to quickly often means you don't chew each mouthful enough and causes problems such as heartburn and indigestion.  Swallowing large lumps of food causes problems for the gut as undigested food ferments, creating toxins and gases that irritate the stomach lining; it also prevents absorption of nutrients and creates digestive problems. Digestive enzymes Digestive enzymes help to minimize indigestion, acide reflux, bloating and gas.  There are three main clasifications of digestive enzymes:
