The phrase "You look good for your age" is the worst possible thing that anyone could say to Jennifer Aniston. She revealed that she dislikes this comment because she currently feels younger, happier, and healthier than ever. Aniston has taken a new approach to exercise, wanting to thrive rather than just be alive.
She used to burn out from intense workouts, so she has started doing less intense workouts and taking better care of her body. Mentioning her age while complimenting her beauty is not something she appreciates. Aniston believes that age should not be a factor in determining someone's appearance or worth.
