Some studies cite this very compelling study as evidence against the Compression of Morbidity hypothesis. This study observes progressively higher prevalence rates of morbidity and disability with increasing age among octogenarians, nonagenarians and centenarians. However, they were unable to determine when in their lives these individuals developed these problems and therefore the work does not describe any differences in compression of disability of morbidity. One of the virtues of becoming a centenarian is the likelihood of compressing the time that you experience disability towards the end of your life. Surviving to ages that relatively approach human lifespan (e.g. >105 years) likely also entails compressing morbidity as well Andersen SL, 2012.
