In an modern society health is suffering due to what I call need of One Solution Belief, that there is one solution for all, one medicine for all health issues, one kind of food for all and one kind of lifestyle will keep you healthy.
How one solution is possible when you and I are different individuals with difference in age, weight, height, place we live, work, fitness, food preferences, general lifestyle. So even if we had same diagnosed illness, the solution will be entirely different.
Hence all the physical issues from cold to cancer, treatment will differ for each individual. Physical ailments are also related to mental, emotional, and energy issues.
