Twaddle, "Lifestyle choices: Diet, exercise, smoking, and alcohol consumption significantly impact HLE. Healthier lifestyle choices generally lead to a higher HLE" are linked to economic factors such as housing ,and provision for recreation.
For instance loneliness which is the feeling attached to social isolation can cause smoking, drinking, and the immobility that often accompanies sadness.
I agree with you. It's much more complex than a single issue, such as fast food or walking to school. In most cases, there are likely to be a number of issues involved, many of which are related to each other. Loneliness and social isolation being linked to substance abuse, unhealthy eating, obesity and also immobility and poor housing is a good example.
