Kankles (or cankles which is the proper spelling) is really a term that occurred inside a movie 'Shallow Hal' in the early 90's. I am sure it was probably around before then, getting used to create fun of others in high school graduation, or to have a laugh at someone's expense. However, many don't find any humor within it in any respect, and is arguably panic or anxiety attack on someone's self esteem. Cankles is when your ankle and calf don't have any curvature hence the merging with the words in order to create Cankles. Even if Kiyosaki is capitalizing on his fame to write a book in a different genre to make much more money, that will not remove for that interesting stories about his and his awesome sister's lives and lessons they learned. I think lots of people ask a similar or similar questions on life, God, spirit, etc. Kiyosaki has now shared some of his questions and also the answers he's found.
