New research using killifish shows that ageing does not always occur gradually, but in distinct steps. This small species of fish lives for approximately three to four months and is therefore often used to study ageing. Scientists discovered that specific patterns in the movement of these fish halfway through their lives can indicate how long they will ultimately live.
The researchers analysed the so-called “movement syllables” of the fish. These are small, repeating movement patterns, comparable to short sentences in human speech. Fish that moved more actively and variedly in the middle of their lives appeared to have a longer life expectancy. Conversely, less varied movements often predict a shorter lifespan.
This research helps to better understand how lifestyle and behaviour can influence the ageing process. Although this study focuses on fish, such findings may also be relevant to humans. Our movement habits could indicate something about our health in later life at an early stage.
For everyone who is consciously focused on healthy ageing, this research highlights the importance of an active lifestyle. Continuing to move and engaging in varied physical activity can contribute to better health and potentially a longer lifespan.
