Psychologists call it "subjective age," how old you feel versus how old you actually are, and there's a strange flip that happens with it. As teens, we tend to feel older than we are. Hit midlife, and that reverses: most of us start to think of ourselves as 20% younger than we are. It's also surprisingly fragile day to day, not getting carded at a bar can make you feel decades younger, until you catch yourself humming along to music from your actual generation and feel it snap back. This isn't just a fun mental trick, either. Feeling younger is linked to real outcomes: it buffers stress, slows the decline in functional health, and is associated with a longer lifespan. One 2023 study found women in midlife tend to feel older than men do, largely because of negative cultural stereotypes about aging women, a real, gendered gap in something that shapes actual health outcomes. ❓ Is there a biological version of "feeling younger"? There is, and it's measurable. One journalist who wrote about her own subjective age had her biological age tested through a blood sample and came back six years younger than her actual age. Psychology has an impact on biology. People who act and look younger have younger biological ages. What drives that gap at a cellular level largely comes down to a molecule called NAD+. NAD+ is the fuel your cells use to produce energy, repair DNA, and regulate aging itself, essentially a battery charge for every cell in your body. It falls by roughly 50% between your 20s and 60s, a decline tied to fatigue, slower recovery, and cognitive fog, the exact "not running like I used to" feeling that pulls subjective age in the wrong direction. NMN is one of the most studied compounds for restoring it. A study in Science gave prediabetic women 250mg daily for 10 weeks and found a 25% improvement in muscle insulin sensitivity, and multiple trials confirm it reliably raises NAD+ in a dose-dependent way, though human lifespan extension from this specific mechanism hasn't been shown yet. If you want to try it, look for a clearly stated 250-500mg dose with third-party testing. This one delivers a research-aligned 500mg dose, third-party tested. 👉 See it here → https://amzn.to/4xnYn1U #ad Feeling 38 in your 50s might not be pure delusion. Some of it may genuinely be happening at the cellular level too.
