In a recent article, UCLA points out that curiosity tends to wane as you get older. That being said, one type of curiosity—state curiosity—can increase into old age.
“State curiosity is what psychologists call the kind of momentary feeling of curiosity people experience when they are asked about specific topics. Trait curiosity [your general level of curiosity], on the other hand, is a personality trait. Some people, for example, might not be very inquisitive by nature, being content to accept things more or less at face value (trait curiosity), but have a passionate thirst for knowledge in specific topics or hobbies (state curiosity). All people possess varying degrees of both trait and state curiosity.”
Individuals who maintain their curiosity as they age can offset or even prevent Alzheimer’s disease. The reverse is also true. People who aren’t curious or interested in the world can be at greater risk of dementia.
