- How about the complexity of life, in general? A child only has that one
- task to accomplish, assuming a fairly normal home life. Children don't have
- to look for practical applications for the things they learn, they just
- absorb the good and the bad with barely any discrimination. Later, adults
- have to justify the effort because they are juggling many other complex
- tasks. A friend of mine, with a photographic memory, told me that memory
- was a function of how complex you life is: the more complex, the less you
- can learn. He felt he was his own evidence. As he grew older, he saw his
- concentration fade as outside interference increased.

- I think you are still keeping the kind of information learned very simple.
- As a person ages, the information becomes more complex. Can you really
- equate learning child-observed physics with learning a programming
- language? I can't.

-
- The unemployed age? When an educated person finds himself obsolete, one
- option is to learn a whole new technology and find a new life. Many people
- do this, encumbered by a complex daily life. I think this overwhelms the
- rate that a child accumulates *complex* knowledge.
