Try to do some mentalrobics every single day!

The average adult human brain weighs 1.3kg (2.8lb). That's twice the weight of a giraffe's brain and three times the weight of a cow's brain. A newborn human baby has a brain that weighs about 350 grams (.8lb), which happens to be the same size as an orangutan's brain.

The size of the brain has very little to do with how smart the animal is. For example, an elephant has a 6kg (13lb) brain, but everyone knows that an elephant is not 5 times smarter than a human. The large size of the elephant's brain is probably how it got a reputation for having such a good memory.
