I don't know if the rules of Feng Shui makes our lives goes better, but why not..we can try it. some of this rules sounds interesting, and I think tat most of they are very logicals. For example, install a cooker next to sink!!! isn't logical, ...or install your bed under a window...very lovely but i don't think is the best place to do it, at most you can catch a cold!
I've bought a book of this tendency, because I like decorate my home and to make more comfortable, and I'm glad to say I've got it.
