Okay, kiddo, have you ever heard of something called "preventable causes of death"? It's when people die from things that could have been stopped or avoided if they had done something differently.
Let me give you an example. One preventable cause of death is accidents. Sometimes people get hurt because they weren't paying attention, or because they were doing something dangerous. But if they had been more careful or followed safety rules, they might not have gotten hurt.
Another preventable cause of death is illness. Sometimes people get sick because they didn't wash their hands or eat healthy foods. But if they had taken better care of their bodies and stayed away from germs, they might not have gotten sick.
And then there are things like smoking, which is a preventable cause of death. People who smoke can get diseases like lung cancer that can make them very sick and even cause them to die. But if they never started smoking in the first place, they might have avoided those problems.
So, in a nutshell, preventable causes of death are things that could have been stopped or avoided if people had made better choices or taken better care of themselves. It's important to learn about these things and do what we can to stay safe and healthy.
