Years of potential life lost (YPLL) or potential years of life lost (PYLL), is an estimate of the average years a person would have lived if he or she had not died prematurely. It is, therefore, a measure of premature mortality. As a method, it is an alternative to death rates that gives more weight to deaths that occur among younger people. Another alternative is to consider the effects of both disability and premature death using disability adjusted life years.

“The years of imprisonment hardened me.... Perhaps if you have been given a moment to hold back and wait for the next blow, your emotions wouldn’t be blunted as they have been in my case. When it happens every day of your life, when that pain becomes a way of life, I no longer have the emotion of fear. ... there is no longer anything I can fear. There is nothing the government has not done to me. There isn’t any pain I haven’t known.”
