Some people feel tired most of the time.
Everyone is affected by varying degrees of stress. Stress can be experienced by those who work in polluted atmospheres, by those who are immobilized at control desks with machines or intruments demanding continual attention, by those who travel coast to coast constantly, by those with mundane, boring jobs, etc. And there are those who turn to drugs or controlled substances for stimulation. The overuse of stimulants is dependency, irritability and lethargy, further reducing energy in a downward spiral. However, there are natural energizers which provide an advantage.
