Plastic surgery is generally recommended only when it seriously affects life. Now it is done for beauty.
There are many examples of failure, too numerous to mention.
Moreover, plastic surgeons have said that plastic surgery is done at a young age and can last for several years. When people are old, their physical function declines, and plastic surgery will not last long. After plastic surgery, it is easy to have side effects, such as double eyelids losing elasticity and drooping, breast augmentation starting to lose shape and exposing breasts.
I suggest you think twice before you act.
