Sometimes, we got a cold, if it is not very serious, we will take some pills by ourself,and we just need to watch the note of the pills, don't need to ask the doctor. In the same, if two person have the same symptom, just one person to see the doctor, and get the same pills share with each other, we also can recover later. Of course, all of these are the special cases, and it is suitable for someone, not everyone. Anyway, I hope everyone will be healthy everyday, including myself.
