I was responding to a commenter who suggested that you'd spend 850 years in the body of a 150-year-old. I was objecting to that idea, but conceding that there might be some unpleasantness left over. I only clarified the timeline of that unpleasantness when you objected. To be clear, I wasn't only talking about scarred skin, but any consequence of aging. I was using excess skin due to rapid weight loss as an example of this type of comorbidity, in which one problem must be dealt with separately from another problem. It may be true that extending lifespans to 1000+ years will require technologies which will also resolve all other age-related issues. It may even be likely. But there is no principle that says it must be so.
