What is Quality of Life?
Quality of life describes the happiness, independence and freedom available to an individual.
How Does Quality of Life Work?
For example, if John Doe hits a dog with his car one night, he may have to consider euthanizing the dog if the veterinarian determines that the dog's quality of life, should it survive, would be very low.
Why Does Quality of Life Matter?
Quality of life is a subjective measure. However, even in the math-oriented world of investing, it plays an important role in setting investing goals and determining one's tolerance for risk. It is also important in matters of insurance and health care, which often hinge on a patient's ability to perform the activities of daily living independently (eating, bathing, dressing, toileting, walking and continence).
