(a). Think of one change you could make in your habits in order to avoid any of/most of the above illnesses.

I fell ill maybe 50 times in the last year. I suffered from cold, cough and fever.
(a) The changes made by me in my habits after suffering from these diseases are:
(i) I will always drink purified and clean water and wash my hands before eating any food item.
(ii) I will live in a clean environment where disease spreading vectors will not multiply.
Example of multiplying vectors are mosquitoes.
(b) One change I would wish for in our surroundings in order to have a healthy society is by making pure drinking water available for the people. Consuming impure water is the root cause of many infectious diseases.
