Of course they both are important. If I can only chose one of tem, I would like to choose over brain. As we all know the beauty will disappear with the times go by. With the over brain, I would know how to dress up, make up properly to make myself more beautiful. Also, over brain will take a lot of other advantages. Last but not the least, maybe without beauty we can find a true love.(may difficult then a beauty finding a lover but if there is one,he/she would be the person who love you instead of your beauty)
