At what age do you start feeling tired and old?

You generally start noticing feeling more tired and older in your late 30s to early 40s, due to gradual changes like slower metabolism, decreasing muscle mass, shifts in sleep patterns, and hormonal fluctuations (especially in women during perimenopause). However, this varies greatly, and significant fatigue can also signal underlying health issues, lifestyle factors (stress, poor sleep, diet), or simply be part of normal aging, with more noticeable declines often occurring after 60, notes WFMZ.com, The Laconia Daily Sun, A.Vogel, Top Doctors UK, valenciamedcenter.com, National Institutes of Health (NIH) | (.gov), Sealions, Healthline, Cleveland Clinic Health Essentials, Everyday Health, Reuters, Alloy, ZOE, YouTube, Simply Supplements].
