Your girlfriend claudia is really excited to try a new machine at her gym. it’s called a ‘growth chamber’ or something. you are naturally skeptical and tell her it sounds like junk science – how can something like that possibly work? claudia is annoyed, and tells you she is going to try it out anyway – worst case, it doesn’t do anything. it turns out that it does work though, way way better than she had expected. claudia’s growth is sudden and dramatic – and it isn’t limited to her muscles!
