A fashionable answer these days, often encountered, is that it is to extend healthspan not lifespan. Here we argue that this is a misguided clich\u00e9. Experimental research with animal models has demonstrated the possibility of intervening in and retarding the aging process, and extending lifespan. This, to varying degrees, increases both healthspan and gerospan, the later-life phase in diminished health. Considering possible equivalent interventions in human aging it would of course be desirable to maximize the former and minimize the latter. However, should a given intervention extend gerospan, given that it would postpone death (i.e., save lives) it would, in many circumstances, be unethical to withhold it. Life in moderately diminished health is generally preferable to death, and this is reflected in the recognized value of many life-saving medical interventions that do not restore full health. Thus, \u201cextending healthspan but not lifespan\u201d is not a coherent objective for research on aging.<\/jats:p>","DOI":"10.1007\/s11357-026-02577-1","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T16:00:09Z","timestamp":1791388809000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Against the \u201cextend healthspan but not lifespan\u201d clich\u00e9"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6653-4676","authenticated-orcid":false,"given":"David","family":"Gems","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ekaterina R.","family":"Iijima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo\u00e3o Pedro","family":"de Magalh\u00e3es","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,10,7]]},"reference":[{"key":"2577_CR1","doi-asserted-by":"publisher","first-page":"19","DOI":"10.5534\/wjmh.180018","volume":"37","author":"A Bartke","year":"2019","unstructured":"Bartke A.
