Already reaching a half century of life in this world. Have gone through countless life experiences. Learned a variety of knowledge. A prepper who always prioritizes readiness in all things. Interested in electronic control and automation, preppers way of life, military technology, and space exploration technology. Started blogging in 2014 to share knowledge and life experiences. Start to write a book when one of the topics intended for the blog turned out to be too long. Just hoping that what’s shared can benefit others
