Almost everyone wants to get smarter. We struggle to improve our  36_ , intelligence and attention. We drink cup after cup of coffee to help us  37_  the day.
 38 __, a new study published in Current Directions in Psychological Science warns that there are 39___ to how smart humans can get.
Each of our body parts develops in a certain way for a reason.  40  _, we are not 3 meters tall  41 _ most people’s hearts are not strong enough to send  42 _  up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __43  , such as the size of the mother’s pelvis (骨盆).

Thomas Hills, one of the authors of the paper, said that   55  all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.
