Well I was referring to people over 70 as a cohort, we are saying the same thing essentially. On an individual level however, adding an illness with 15% mortality on top of all the other things over 80s can get is a big deal. 80+ year olds are a varied cohort, and some are reasonably healthy, with multiple years left to live. The hip fracture data is biased because frail people with other problems are more likely to fall.
