People who often get ill should pay more for a healthy lifestyle. I partly agree, because it depends on the immune system and also on the country.
Firstly, I want to talk about the immune system, because every person has his own immune system, and it depends not only on food, but also your luck. A person can be born with a bad immune system, and it looks like you need to be fortunate to get a good immune system. In addition, everyone can upgrade his own health that a healthy lifestyle, for example, spend more money for healthy food which has many vitamins and many other methods of how you can change your lifestyle.
Secondly, it depends on the country where the person lives. For example a person can be born somewhere in Africa, where people have challenging lifestyles which includes surviving without food or water for days, and therefore have bad health. However, it has some benefits. For example, they will have better health than another person if they change their country. Thus, if you have been born in a bad country, it does not mean that you will have bad health for your entire life, because you can do some fitness, which has many benefits for your health, such as decreasing the chance of a stroke, upgrading the immune system, and many others.
In summary, it depends on the country and your immune system. Nonetheless, you can upgrade your immune system with fitness if you do not need money for it, but if you have money, you can buy healthy food. Also, you need to change your habitat for a good life.
