Document Summary

Crystallized intelligence: intelligence in which they are the types of problems that you solve all the time (knowledge about the world general) Fluid intelligence: intelligence that is based on speech with which you solve novel (new) problems (how to attack the problems/how fast) Knowledge base that you build up when you are young is the reserve. Some people have amassed so much crystallized intelligence that it takes longer for degeneration to take place. People who stay active and refresh their memories age gracefully. If you keep using brain, you are less likely to lose it. Some people have aging problems due to genetics. High stress affects all body cells, especially hippocampus (lose volume in the hippocampus, which stores memories) Exercise makes cognitive decline less steep because you do not lose much volume in the frontal, parietal, and temporal areas. Processing speech decreases and reaction time is slower. Abstract and complex problem solving decreases especially when solving new problems.
