Normalize middle age and Elder's bodies. People gain some weight for survival in case we get cold or ill as we get older. And we feel stronger than ever because we've built a variety of things and hauled plenty over the years. Normalize our wisdom in a wrinkled package. We have the knowledge in our heads others seek. So many experiences and memories of how things used to be, looked and worked all over the world. "Older folks don't know anything" makes zero sense.
