What do you mean? If my problem is that I have a big mole or skin tag on my body, or my nose looks weird, then surgery absolutely solves my problem.

If the mole or skin tag is detrimental to your health, or if you nose's pathway is giving you trouble breathing, then yes, I'm in favour of an operation.

If it is just for cosmetics you are not doing yourself a service. Most of the time people do it because they have a low self esteem.

What’s wrong with making cosmetic changes solely to improve low self esteem?

And you might get a free bonus with your new nose - an antibiotics-resistant strain of bacteria. ;)
