Sources: Peak age data from Hartshorne & Germine (2015) — "When Does Cognitive Functioning Peak?", Psychological Science. Vocabulary/knowledge peak: Virginia study of 50,000 participants. Emotional intelligence: Carstensen et al. Stanford. Learning rate modelling uses deliberate practice theory (Ericsson et al.) with age-adjusted neuroplasticity curves. Compounding skill model inspired by research on expertise acquisition. Individual variation is enormous — these are population averages. Your 50-year-old friend who learns faster now than at 14 is backed by science, not just optimism.
