📖 The Psychology of Time

As we age, each year becomes a smaller fraction of our total life experience. To a 5-year-old, one year is 20% of their entire life — an eternity. To a 50-year-old, a year is just 2% — it flies by in what feels like moments. This proportional theory explains why childhood summers felt endless while adult years seem to vanish. Our brains measure time relatively, not absolutely.
