To utilize a life expectancy calculator makes you think about what is important in life. While a bit daunting, these calculators clearly demonstrate the important health factors of a long, healthy life, and help you to make some positive plans for the years ahead.
Also, calculators like these, can help you to take the emotion out of lifelong decisions and observations. For example, as I dealt with a loved one's illness, I utilized one of these calculators. The calculator demonstrated to me that what I saw as a dramatic impact of health effects was actually a much less worrisome effect--that brought me comfort.
Data of any kind, if accurately collected and analyzed, can help us to see situations with greater clarity--these data points can also help us communicate with care givers and others. For example, when using another one of these calculators, I easily noted the categories important to making a good decision as well as how my loved one was rated in those categories. That will help us to make good decisions about my loved one's care.
As I often write about, taking the long look at life, helps us to then pull back and live each day more fully. This far-reaching to present-day elasticity of perspective is a positive way to move ahead in life. Onward.
