Moreover, contrary to opinions often expressed on Hacker News, the demographic data from all countries with good data show that increases in healthy lifespan are occurring at all ages, even age 40, age 60, or age 80. "Humans are living longer than ever before. In fact, newborn children in high-income countries can expect to live to more than 100 years.
