Today, a college-educated person with a comfortable income is likely to live into their 80s. A life this long can be divided into four periods, averaging roughly 8,000 days each. The period from birth to college graduation is approximately 8,000 days. College graduation to midlife, or 46 years of age, is another 8,000 days. Midlife to the retirement age of 66 is also 8,000 days. After that, there’s generally another 8,000 days for retirement. Retirement planning doesn’t exactly take into account the realities of an 8,000-day retirement; a script hasn’t been written for that final, but still lengthy, phase. Learn MIT AgeLab’s insights to help investors prepare for an 8,000-day retirement. Help investors reduce uncertainty and prolong their independence so they can live the lives they aspire to.
