Guiness Books Of Records has official named Mehmet Ozyurek from Turkey the biggest nose in the world. This event took place in the anual nose-messuare competition in Turkey in 2005. It's 8.8 cm long. I think I might reach him lol
You know that nose is growing all the time man live. So your nose will be bigger when you are old than now. He has potential to get to 10 cm
