Let’s imagine that Franklin D. Roosevelt had possessed the same gift for longevity as Jimmy Carter and lived until he was 100. He would have died in1982, in Ronald Reagan’s second year in office.
Most likely FDR would then reside in my consciousness in roughly same way Carter does for my children, who are in their twenties. Remember that time he was at our same gate at the airport and we thought about trying to talk with him but decided that might be weird? In other words, FDR would seem like a somewhat fuzzy figure but not an impossibly distant one — not a sort of marble statue from a whole other era.
