Epigenetic alterations as a hallmark of aging can be thought of as changes in the instructions that tell our genes when to turn on or off. These instructions are like tiny tags on our DNA that control how genes function. Over time, these tags can get altered or messed up, much like scribbles on a recipe that make it hard to cook a meal correctly.

As we age, these epigenetic tags can change, leading to genes being turned on or off at the wrong times. This can affect how our body functions and ages. It’s like having a musical instrument that used to play beautiful music but starts producing off-key notes because someone altered its settings. Epigenetic alterations are a way our body’s control system for genes can become less precise with age, potentially contributing to various age-related health issues.
