The Gompertz–Makeham law of mortality describes the age dynamics of human mortality rather accurately in the age window from about 30 to 80 years of age. At more advanced ages, some studies have found that death rates increase more slowly – a phenomenon known as the late-life mortality deceleration [2] – but more recent studies disagree. [4]
Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
Thus the force of mortality at these ages is zero. The force of mortality μ(x) uniquely defines a probability density function f X (x). The force of mortality () can be interpreted as the conditional density of failure at age x, while f(x) is the unconditional density of failure at age x. [1]
According to Book Marks, the novel received "rave" reviews based on fourteen critic reviews with twelve being "rave" and two being "positive". [2] In Jan/Feb 2015 issue of Bookmarks, the book received a (4.0 out of 5) based on critic reviews with a critical summary saying, "Still, considered essential reading as our population ages, Being Mortal "offers a cautionary tale of what can go wrong ...
Throughout the world, mortality rates have steadily decreased decade upon decade [21] [22] that has historically changed our meaning to death. [3] As age-related illness and diseases has become part of our lives, what makes a "good death" socially has altered along with advancements in medicine and technology.
Black is the color of mourning in many European cultures. Black clothing is typically worn at funerals to show mourning for the death of the person. In East Asia, white is similarly associated with mourning; it represents the purity and perfection of the deceased person's spirit. [7]

The Lee–Carter model is a numerical algorithm used in mortality forecasting and life expectancy forecasting. [1] The input to the model is a matrix of age specific mortality rates ordered monotonically by time, usually with ages in columns and years in rows. The output is a forecasted matrix of mortality rates in the same format as the input.
