In Chap. 6 , I introduced the narratives of Miki and Mikiko, who became imaginary future persons through their own efforts. After the workshops in Yahaba Town, I noticed that older people were more likely to become imaginary future persons and come up with creative ideas. Initially, I wasn't sure why this was the case but after reading some neuroscience literature I learned that the brain regions and networks used to think about the past are almost identical to those used to think about the future. This led me to wonder: might the extensive past experiences of older people help them more easily imagine future experiences? Conversely, might younger people find it more challenging to become imaginary future persons and realize their own futurability?
