Bholu's neighbour doctor asked him to drink boiled and cooled water for few days. Bholu instinctively asked "Why?". The doctor replied, "Prevention is better than cure". Help Bholu to understand the meaning of this phrase.
We can prevent the entry of certain microorganisms in our body simply by adopting clean habits like washing hands with soap before eating food, avoiding unhygienic and stale food and maintaining personal hygiene. Boiling water for 20-30 min will kill the pathogens present in it, making it safe for drinking.
