《Do you believe there is a doctor in our body》
Most people laugh when they are told that there is a doctor in our body.A doctor,in their eyes,must be wearing white uniforms all day,with gentle smile on their faces,walking steadily along the long corridor in the hospital.However,believe it or not,truly,there is a doctor in our body,a professional and diligent doctor just for you.
This doctor is with each of us all our lives' time,no matter when we are too young to dress ourselves or too old to support ourselves,he never leaves.This doctor not only cures us sometimes,but always take good care of us as well.When you are wounded in your finger,your arm,you begin to bleed,take it easy,you don't need to go to a hospital and see a doctor,you don't need to pay,a couple of days later,you find you are totally fine!When you have a headache,a toothache,you feel like sleeping for a while.Then you wake up refreshed and comfortable!When you feel hungry,thirsty or tired,you are instructed to do something,such as eating some food,drinking some water and having some rest.Have you ever wonder that who is the maker of all these special instructions?It is your doctor who is inside your body!He is always ready to give definitely special orders to make you better.
Sometimes,you are angry about someone or something,or you are excited on victories,even you are sad for the death of your lovely dog,after a short period,you calm down yourself,you smile again.Who persuades you?Who is the considerate friend?That is the doctor inside your body!He just tries the best to calm you and console you.
Well,dear friends,let's just get along well with our private doctor!He is one of our most reliable and helpful friends!
