Researchers have investigated how the way fish move during their lives is linked to their lifespan. They followed killifish, a rapidly ageing species, and observed that ageing does not occur slowly, but in clearly recognisable phases. They also noted that the movement pattern in the middle of life gives indications of how long the fish will still live.
The study shows that healthy, varied movement in middle age is associated with a longer lifespan. Changes in movement appear to be important signals that accelerate the ageing process. This provides a new perspective on the dynamics of ageing, in which not only age itself, but also behaviour and lifestyle play an important role.
Killifish were chosen because they have a short, well-defined life cycle. This allowed scientists to map out the entire ageing process thoroughly and look back at early signs that indicate health at an older age. This is comparable to humans, in whom exercise and vitality are also important indicators.
For people who are consciously focused on healthy ageing, this is an interesting development. It suggests that monitoring and stimulating active movement in daily life, even at a relatively young age, can contribute to a longer and healthier life.
