Our lives are often perceived as a linear journey of decline, but research is now suggesting that ageing might not be as straightforward. Instead, it appears to consist of distinct phases, each marked by significant biological changes.
One recent study published in Nature Communications shed light on the brain's developmental stages, identifying five eras separated by turning points at age nine, 32, 66, and 83. Interestingly, a prolonged "adolescent" phase from age nine to 32 emerged, characterized by stronger and more efficient brain connections that persists well into what we typically consider adulthood.
This finding is just one of several recent studies exploring ageing across various bodily structures. Other research proposes rapid ageing in organs around age 50, specific changes in metabolism and systems at 44 and 60, or four distinct ageing phases for the skin. Additionally, the adult immune system has been found to age in two phases.
These discoveries are largely thanks to advances in "omics" research, which enables the rapid measurement of an organ's molecular profile. This growth in understanding is also reflected in increased funding and interest in ageing research, likely driven by the growing proportion of elderly populations.
While many studies remain underpowered and should be interpreted with caution, the cumulative evidence suggests that ageing might not be a linear process but rather a dynamic journey. This raises questions about the potential benefits and drawbacks of intervening against ageing.
Some researchers are eager to develop anti-ageing treatments based on these findings, but this approach may be misguided. Instead, prioritising wellness over raw longevity could lead to better health outcomes. By identifying specific biological changes and tailoring interventions accordingly, we might be able to apply existing measures more effectively, whether they're disease-specific or preventative.
Ultimately, the goal should be to maintain a healthy and active life, rather than simply trying to halt or reverse ageing. This approach may result in longer lives, but it's essential to reframe our understanding of what it means to age and focus on overall wellness rather than solely chasing longevity.
