Fantasy vs. Science Fiction

Science fiction is for the mind, while fantasy is for the heart. In general, fantasy can also be different. If I spend time on a book, I want to get the maximum benefit. Fantasy usually has a very positive vibe. People often identify with their favorite character, and after reading, a piece of that energy remains within you. But what's the point of fights and aliens? Well, sometimes you come across an interesting idea. But mostly... it's just a way to pass the time with some interest.
