I cam across this article about these guys that were all appearances "Handsome" and yet decided to go through all kinds of plastic surgeries to make themselves look weird. The author thought it was mental illness but is it? I read it here - Source 1f.
Why would they want to do that to themselves unless they had some kind of mental illness as has been suggested. Then again does everyone that does plastic surgery have mental illness? Where is the line that you don't cross?
