People who cause their own illness through lifestyles and poor diets should have to pay more for healthcare. To what extend do you agree or disagree with this opinion?

It is said that an unhealthy lifestyle put an impact on people’s illness and the better food they eat the better their health is. I believe that people should maintain their health by paying more attention to improving their lifestyle and their daily diets.
When children stay up late to watch television or play games on their smartphones, this extremely harms their health. They will feel exhausted the following morning and they can’t focus on their lessons at school. If this issue is not be prevented, they will get sick. In addition, people who addict to coffee, wine, or drugs will turn their bodies into bad conditions. They cannot concentrate on their work, so they may lose it and their relationship with their relatives or friends will be bad.
One of the factors that have an effect on people’s health is having a good diet. The housewives should cook nutritious meals for their families. Young people should not eat more fast food or processed food to prevent obesity. They have to learn how to cook from their parents and get to know about nutrition before they leave their home for their own life.
From my point of view, I totally agree that people will get sick if they do not maintain a healthy lifestyle and they should learn how to prepare healthy meals for themselves and their family.
