helen keller and joy

how was helen keller so smart? so intuitive? so new age earth goddess knowing? it just seems so unlikely. she was the first deafblind person to get a college degree. extraordinary. and even as a deafblind person who could not see and depended on touch for everything, she could state something so concise as this? was her heart more able because other senses were diminished to the point of not existing? blind people have a greater sense of hearing.. does someone deafblind has enhanced heart? i'm guessing probably.
