[EX Q]: I have very hard water where I live. I use this once or twice a week and it really helps remove the build up on my hair. I'll definitely keep using this.
[EX A]: positive

[EX Q]: I slouch at work sitting at a desk all day. Was trying to find a good solution to help alleviate the slouching and back pain. This posture corrector has definitely helped! I am sitting straighter and the pain has lessened.This posture corrector has given me strong support for my back, without restricting my movements.
[EX A]: positive

[EX Q]: Suppose modern technology were the figment. Suppose you were writing a technology-fiction book about teenagers attending an Institute of Technology. Would the classes be "History of Technology", "How to Use Technology", and "Get in Touch With Your Inner Technologist"? Would fights between students take the form of teens using technology on each other? Would the students self-identify as members of Electricity clans or Chemistry clans? Seems threadbare, but you cold still write a book worth reading if you gave it a real plot and interesting characters. This book is the fantasy equivalent. It has the tired recycled tropes ("I'm a Witch, and I'm going to show off by casting a glowing light!") without the story that would redeem them.
[EX A]:
negative
