Who counts as middle-aged now? They are younger than you think.⁠ ⁠ People in their 20s and 30s are hitting milestones such as marrying and buying a home later than past generations, but the expectations to do so are creating stress for them. That stress makes them feel older, as do mounting concerns about job security, debt, child-care costs and caregiving for older relatives.⁠ ⁠ Middle age is typically defined as ages 40 to 60. But about 20% of younger people ages 25 to 34 feel middle-aged, according to a study by Horizon Media, a marketing services agency. The average 25-year-old says middle age starts around 37 and ends at about 53. Conversely, the average 65-year-old says it starts at 46 and ends at 62, according to the study.⁠ ⁠ Both groups mostly agree on the physical signs of middle age: skin changes, aches and pains and worsening eyesight. ⁠ ⁠ “Young people are feeling older and feeling pressure a lot sooner in their lives,” says Tirrell De Gannes, a licensed clinical psychologist at the Thriving Center of Psychology, which surveyed millennials and found that 1 in 10 experienced a midlife crisis around the age of 34.⁠ ⁠ Read more at the link in our bio.⁠ ⁠ Photo Illustration: WSJ, iStock
