The average adult human brain weighs about 3 pounds.
Brain Size Variations
While the average brain size is about 3 pounds, there are variations depending on factors like age, gender, and overall body size.
- Age: Brains grow until about age 25, then start to shrink slightly.
- Gender: Men tend to have larger brains than women, but this doesn't necessarily mean they are smarter.
- Body Size: People with larger bodies tend to have larger brains.
Brain Size and Intelligence
It's important to note that brain size doesn't directly correlate with intelligence. Intelligence is a complex trait influenced by many factors, including genetics, environment, and experiences.
