I find it difficult to agree to this statement from a holistic perspective since there are many unknowns that the average individual has little to no control over. For example, how do you, as an individual, can control the air quality in your vicinity [1]? the water quality [2]? soil? pesticide/procurement/logistics of food? Work environment? Family environment?

What do you do and how do you control the quality of all these things for a long stretch of time (1, 10, 30 years?)? In theory, as you have more income, you may have more control over some of the areas above, but the reality is that some factors are still difficult to control/ balance.

There is still a major part of acute illnesses that are directly associated with choice in the areas of dieting and exercise, so do not take my response as a full counterargument to your opinion.
