प्रश्न
While playing, Amit hit a wall. His forehead was swollen. Didi immediately folded a scarf (4-5 times), blew on it, and kept it on Amit's forehead. Why do you think didi did this?
उत्तर
After hitting on the wall. Amit’s forehead would have swollen and become hotter. Didi folded a scarf, below on it and kept it on Amit’s forehead because she might have learned this from her elders but it is a wrong practice. Actually, it does not cure the pain, but on blowing, the scarf becomes a little warmer and gives some relief to the pain and swelling.
