of a paper by Charles Mullin:

> about a 5 percent reduction in relative terms in the
> mortality hazards per successive cohort.
Any idea what this fellow means by "cohort"? I've always understood it to
mean the group of people sharing a birth-year. Does this mean 5% per year?
I'd like to believe that it does, but this seems very optimistic.
