There are quite a number of things that people take for granted today, regarding their health, at least in developed nations, like the United States. The majority of the population doesn't think much about the possibility of starving or being malnourished. If we suffer an injury, we can find treatment at a nearby pharmacy or convenience store. For something more serious, medical care is generally not too far away along roads that are kept in good repair. The same thing if we get sick.
