The lifetime benefit from Social Security is calculated to be the same regardless of what age you start receiving benefits. So someone starting at age 62 isn’t getting anything more or less, over the lifetime of payments, than someone starting at age 70. That being the case a person might as well start at age 62.
Last time I looked, the crossover point is around age 84. If you die before then it was best to take the smaller payment early. If you die later it is best to wait to take it. Whether you will live to be 84 is a guess based on your health and family history.
