An lot of brute force memorizing details that everyone else would look up. Biology feeds to medical fields where you have to have details you rarely used memories because you might be doing surgery on someone who is slightly different from typical and have to figure out what that thing in the way is - can you safely move/remove it or not. (I'm not a doctor, real doctors can come up with plenty of much more likely real world examples of situations where you don't have time to look up some detail)
