Like most things, there are legitimate and necessary uses for plastic surgery. But also like most things, many people go overboard with it. I see news stories from time to time showing pictures of movie stars who destroyed their looks with plastic surgery. Some say it's an addiction.
I predict in a few years we will look back on women who have giant inflated boobs, lips, and Botoxed faces, and say WTF were they thinking?
Same with Asian women who whiten their skin to the point of looking like cadavers. I've seen Asian girls whose eyes were so big they made my eyes water to look at them. Fortunately the obscenely giant boob craze has not caught on in Asia, at least so far.
