Why do old people want to look younger?

In many cultures today, it seems that only youth is worshiped and admired. As people age, they may believe they will face discrimination at work if they look "too old." Or they may want to have a new relationship and believe that looking younger will help them to be more attractive. In previous generations, older people were treated with respect, but the popular culture today seems to prefer a youthful appearance; this makes some older people feel they need to have plastic surgery or wear very contemporary fashion so that they will not seem out-of-date.

On the other hand, not all older people feel this way. Some are proud of how they look and are comfortable with the aging process, even if the popular culture focuses on how to look young.
