 Resources and monies (-dG) are required to achieve the gains, or increases, in life expectancy.If the resources are wisely spent, i.e., below the limit of benefit SCCR, then the gains in life expectancy will be sufficiently large that there is a net increase in the Life Quality Index (LQI).In contrast, if inordinate sums are spent on activities that do not save lives or result in only meagre life extension then there is a net decrease in the LQI.
