I'm sorry to hear that you often catch a cold. You are in poor health. I want to tell you some advice on how to keep healthy. First, do more exercise. This is good for your health. Second, you should have healthy eating habits. You should eat more vegetables and less meat. They are good for you. Third, you should wash your hands before meals. Fourth, don't go to crowded places. I hope this suggestion is good for you.
Best wishes.
