Does rhinoplasty REDUCE your life span:(?

Let's face it: the human nose was NOT meant to be cut up and sewed back up into place. That's an extremely stressful event for any human body. Could this type of trauma shorten/reduce life span at all? It's a difficult operation and so are there any negative long term, damaging effects? Also, what is the effect of having fake pieces sewn into your nose? Like when your nose ages and starts to droop? Do you have to keep getting nose jobs like Michael Jackson to fix it! :/
