There is a "hot" topic in our class today

Our speaking class' topic was 'Plastic Surgery-Agree or Disagree?'
In group discussion,five of us all agree that it is necessay for people who had an accident on his/her body.

But for somebody who just wants to be more 'atractive' or 'popular' by others.We had a hot argument.

For the members who agree to have the plastic surgery on normal people,it was said that plastic surgery could make them more cofident.

I understand that every adult has the right to make his/her own dicision to have the plastic surgery or not.
I won't blame the person who has done the surgery.But if they are my friends or relatives who want my advices.I will ask:"Is this the most important thing for your life?""Have you thought about the side-effect?'
'Do you rely on your appear for your confident?'

Actually,something or someone is beautifull or not,different people might have different ideas,right?
Look at this photo here,I recon that many people would say he/she is lovely!

What I heard was some people did not like big nose and small eyes,do you like you big nose and small eyes,Miss/Mr Koral?

Is she pretty or ugly?What is your opinion?
