Goldberg proposes the intriguing concept of a cognitive personal trainer (analogous to the personal trainers in physical fitness centers) who can help with what's here and now in the cognitive life of the elderly. We call them teachers in the early part of our life—folks who can diagnose cognitive needs and guide their resolution. One can imagine that many older folks who suddenly confront a new life in retirement or in infirmity might need help that's analogous to what they needed when they began a new life in Kindergarten.

As our lifespan increases, it will become increasingly important to enhance our cognitive as well as our physical well-being. Goldberg has written an excellent practical book on how we might achieve this. Next month's column will explore possible educational applications of the three perspectives of intelligence discussed in this and the two previous columns.
