Learning almost anything sufficiently new will do that to you. Dabble in calligraphy and letters will never quite look the same again. Get into dance or poetry and you'll appreciate entirely new nuances to music.
There is more to this argument, but this is a good start, I think.
Skills, in a broader sense expand how and what you experience. Language does this to how we experience communication and expression. Reading in general does this too, but in different ways.
Like how you can't hear a word you know without understanding its meaning, expanded beyond language.
