That being said, changing your God given body, like getting a nose job or a lip job, is... well, it's not wrong but it's not entirely right either. That still doesn't give us the right to judge their choices or call their new look a mistake. It hardly matters if they do it to impress others as long they are happy with how they look.
You never know how strong you are until being strong is the only choice you have.
What is not good is for the sake of imitating the celebrities and actors, people undergo intense body building, take steroids, spend large sums of money which they can't or even undergo minor surgery. This should be avoided because it harms the person's health and finances that is not worthwhile in the long run.
