Research indicates that men age faster than women, with biological evidence supporting this difference. According to a study published in "The Journals of Gerontology: Series A," men's bodies are, on average, four biological years older than women's by the time they reach their 50s. This gap is also apparent in younger men, even starting in their 20s.
While men may age faster, they are not necessarily weaker than women. Some evidence suggests that men's bodies may be more resilient to certain diseases and they have a longer reproductive lifespan than women. However, this is just one aspect of the complex picture of aging, and further research is needed to fully understand the differences between men and women's aging processes.
