One thing not included in the table is death and dying. Death can occur at any age, whether from old age or diseases like cancer. The stages of life are general guidelines, but the timing and reasons for death are different for everyone. Life expectancy has varied significantly throughout history and across different regions of the world. Factors such as advances in healthcare, nutrition, sanitation, and public health measures have played a crucial role in shaping life expectancy over time.
