We all know the popular saying , ' Health is wealth ' . By health we do not mean the absence of physical troubles only .
But it is a state of complete physical , mental and social well - being . The loss of health is the loss of all happiness. Mahatma Gandhi also says , " it is health which is real wealth , and pieces of gold and silver " .
Good health depends on several things . Fresh air and sunlight are very important for our health . A dirty and damp atmosphere causes lots of diseases .
