Hi, my name is John Whitfield. I'm working as a writer. I like to write articles on different subjects. It helps me to enhance my writing skills and not to be bored about my job. Also it helps me to become more universal facing topics from 'what's my attitude to this book' to 'nanotechnologies based on graphene structures'. I wanted to write books, but found more interesting writing activity. My hobby is traveling and I was in many countries. Thanks to my job, cause all I need is my laptop, that gives me an opportunity not to be tired up by 'sit in your office' duty.
