Answer:
We need to have good resistance to prevent infection of diseases. Resistance is the body's ability to fight off infections and diseases by producing antibodies and other immune system components to protect itself. Having good resistance means that the body is better able to fight off infections and diseases, which helps to prevent them from occurring in the first place. Building up resistance can be achieved by getting adequate amounts of rest, eating a balanced diet, exercising regularly, and avoiding stress. Additionally, regular vaccinations can help to build up resistance to certain diseases.
