«The inflammatory ageing clock (iAge), reported on 12 July in Nature Aging1, is one of the first tools of its kind to use inflammation to assess health.Other age clocks have used epigenetic markers, chemical groups that tag a person’s DNA as they age and are passed along as cells divide.»

«iAge is based on the idea that as a person ages, their body experiences chronic, systemic inflammation because their cells become damaged and emit inflammation-causing molecules. This ultimately leads to wear and tear on their tissues and organs. People who have a healthy immune system will be able to neutralize this inflammation to some extent, whereas others will age faster.»
