 Without good health, little else matters. Good health affects weight, skin quality, teeth, hearing, eyesight, and enjoyment of life. It also affects your energy, controls your allergies, and helps prevent degenerative diseases. For a more healthy life, drink water from glass or stainless steel rather than from plastic bottles. Plastic outgasses contaminants that accumulate in the body. Eat food that's grown or raised naturally and prepared with little to no processing or toxic chemicals.
