Let's put aside God on this, And let's think of human behavior, Have you seen an Human child acting like an animal? have you seen adult human acting like an animal? have you seen an animal acting like a human? have you heard of anyone who had nose surgery? how about breast surgery? or orthodontic work? ETC.
was this changes necesary to human's well being? would this imperfections damage this being life? is so at what level? are they of life threatening?...

this changes were done because this being was not comfortable with its natural characteristics, therefore this being in the pursue of accomplishment wanted to be seem as normal in front of the other beings, and it changed what it thought it was of imperfection.
This is not bad but it was not necesary. They just didn't like what they had and wanted to change it, which goes againt nature, because you weren't form ( born ) like that, you didn't had pierced ears,pierced belly, pierced eyebrown, etc. though its painfull but necesary for some people's mind.

My point, just accept yourself like you are, you know what its good and bad, you choose what will it be. look under your underwear and accept what you see there. that's how you were form and that's how you were mean to live here for some time. untill we die, then who knows exactly what happen next. but one day we will find out. this is nature.
