I want my nose thin and sharp without any surgery, but only by yoga and exercises ? Can it is possible ???

Yoga and exercise will not change the shape of your nose. It is likely that you will need a surgical intervention. Best, Dr. Emer

  A surgical rhinoplasty is required to narrow a wide nose. To narrow nasal bones requires osteotomies placed in them, and manually narrowing the bridge line. The nose is composed of  bone and cartilage which must be surgically adjusted in order to make the required changes. For more information  and many examples, please see the link and the video below

I also want to be a multi millionaire without working or winning the lottery. To change your nose you need surgery. Anything else won't work - unless your name is Harry Potter.
