People who neurotically obsess over danger and risk and awful things are not well.
Nothing bad will ever happen to you, and if does all of your anxiety-driven role play preparation goes out of the window. It's all worthless.
It's easy to talk when there's no pressure, but under severe stress, the world looks very different.

Taking care of yourself is far more than worrying about how you're gonna be dead one day.

I think it largely depends on circumstance and necessity for some of those. Everyone should ideally pay attention to nutrition and health, but that can very much be a privilege outside of their reach. It's also difficult for most people to think of potential distant payoffs if they do things like eat healthy. If I eat a carrot today because I read it's good for eye health there's not going to be any proof it ever helped me, even in 30 years of eating them daily. I'll develop an eye issue due to genetics/environment or I won't, we can't just look at our stats like a video game character and say we successfully resisted a disease due to diet.

If you find yourself in situations where self defense or street smarts is needed then you likely don't have the time or money to invest in nutrition. Self-defense stuff can be good exercise and also good for your mental well being, but if you feel that you're in a safe area I think most people don't really want to think about ever needing it. It's one of those "out of sight, out of mind" things.
Ultimately people do the bare minimum of what they think is necessary to survive. It's just our nature to take the path of least resistance.
