Why Do we fall ill?

Answer 1

As with machines, our bodies develop faults too. In some cases, we become ill because we don't have enough of the right materials, and other times it is because something has got in that our bodies can not manage. We can develop many illnesses because of vitamin or mineral deficiencies, and we have other illnesses because our immune system failed to protect us from virus, bacteria or fungus. This is why a well balanced diet is needed and other safety measures such as washing hands, etc is important.
