Plastic surgery is a personal choice, but for many actors, performers, celebrities, etc. maintaining one's looks goes with the territory and is for all intents and purposes an important aspect of their job. Personal trainers, nips and tucks, highly paid hair stylists and makeup experts are all part of that - their looks are part of their stock and trade. Some are more successful than others. Raquel Welch looks good - there have been some plastic surgery messes - Melanie Griffith comes to mind.
