I’m writing to ask for more information I want to know about virtual reality. I am really amazed by what you said and I was wondering how the technology can be used in my classes. Besides, I’m interested in its medical applications as I always dream of being a doctor in the future. Can you give me clearer explanations? Is it possible that some day people may focus only on the virtual reality rather than reality? If so, will it be a huge threat to human beings? I would appreciate it if you could write back.
