- We think a lot about living longer, but that means we will also have a longer period of frailty and infirmity, which isn't optimal. Moreover, with geriatric populations projected to expand by 350 fold over the next 40 years, healthcare costs will be unsustainable.
- We were interested in understanding how health span of animals is regulated, and whether the microbiota plays a role. The microbiota, which is composed of bacteria inside and on us, when dysregulated (called dysbiosis) contributes to disease; the question we asked was whether it could also contribute to healthy aging, and how.
- We showed that animals of widely divergent phyla and separated by hundreds of millions of years of evolutionary time, all utilize indoles to regulate how well they age; in short indoles make older animals look younger by various metrics, including motility, and fecundity.
