No any expert, professor or doctor can explain exactly how our body heals a wound but our body must know exactly the way she heals a wound.
Normally when it takes long time for our body to heal a wound, there must be a difficult sickness behind and it takes time to find out. This is what we know. What we do not know is why it is like that.
Look at the picture above, what fantastic human body can do is beyond our imagination, but what we know about her is very limited.
We are all so different from each other.To understand special you, you have to work on your special body. No one can know your body better than yourself. What you need is just to pay attention to your body daily.
