The document discusses Howard Gardner's theory of multiple intelligences and how it relates to adult learning. It describes Gardner's theory that individuals possess different combinations of intelligences including linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, and naturalist. As adults age, their abilities in various intelligences may decline due to poorer vision, hearing, memory, and physical limitations. This makes acquiring new knowledge and skills more difficult compared to younger adults.
