Fluid Intelligence vs Crystallized Intelligence

I've got to say, I think I possess a bit more crystallized intelligence than I do fluid intelligence. But I could be wrong. I thought that this section of the chapter was interesting, and it allowed me to really understand the difference between the two forms of intelligence. It makes sense to me that older people begin to lose their fluid intelligence, while their crystallized intelligence may be abundant. The textbook talked about how we often use the word quick to describe someone who we see as smart, while we use the word slow to describe someone we feel is a bit dumber. This really does explain which intelligence we rely on more in terms of first impressions. However, I bet we've all met that older person, or perhaps even a younger person, who may not be unmatched in fluid intelligence, but they know quite a bit about an array of subjects. Those people who seem to know every fact within a certain topic are also thought of to be extremely smart, right? I just think it's interesting that we can determine whether or not someone is "smart" based on two completely different measurements of intelligence. It seems that the topic of intelligence and how we measure it will continue to change as the years go on.
