For millions of years, man spoke only to what he could see. Suddenly, in just one decade, 'seeing' and 'speaking' have been separated. We think we're used to it, yet we don't realize the immense impact it's had on our reflexes. Our bodies are simply not used to it. Frankly, the result is that, when we talk on the telephone, we enter a state that is similar to certain magical trances; we can discover other things about ourselves.
