Growing means you're making new cell, aging is when you're cell seems tired and stop regenerating or being eaten by other cells.

- pier25 4y agoAren't cells replaced periodically?
- space_fountain 4y agoYes, but in a very controlled way, typically with a fixed number of total devisions. Understanding aging is a slow process, but as far as I know current thought is that it has a lot to do with that replacement slowing down for a variety of reasons. This slow down seems like it may somewhat be a tradeoff with cancer though. Cells that divide too robustly end up cancer, cells that sort of shutdown instead are known as senescent and seem to contribute to aging
