We all grow older, but there are definitely ways to do it more gracefully and happily. Model Marie Helvin, who'll be turning 58 this year, recently wrote about how she's "kept her looks" as she's aged. Her advice is pretty sound: wear sunscreen, exercise, eat well, get enough sleep, moisturize, don't smoke, eat less red meat. They're all things that just make you healthier and better-looking in general.
It remains to be seen whether all of us can have results like Marie's. Healthy living is key, but genes have a lot to do with how we age. How much of aging do you put up to following good health advice like this, and how much do you think is due to your family tree?
