If you happen to’re in any respect focused on supporting your longevity efforts (like we’re), you could have heard that having shorter telomeres is an indication of organic ageing—and thus, having longer telomeres is an indication of residing an extended life. These little chromosomal caps assist shield our DNA from harm, and measuring the speed of their decay over time can provide us an correct prediction for lifespan. 

Whereas we don’t fairly know if telomere shortening is the reason for dying or just a byproduct of it, one factor is for sure—telomere size is, actually, related to organic ageing. And because it seems, having longer telomeres is linked to a diminished threat of dementia as effectively.
