Why do some people look much younger than their age?
I'll answer this on behalf of my wife who is one year younger than me but looks about 15 years younger.
Despite being 45, she is constantly mistaken for a woman in her 20’s, is still challenged for ID in certain places, and generally attracts plenty of looks from young lads.
She attributes it to lifestyle and genes. Now when I say lifestyle, I do not mean healthy living from a nutrition or exercise point of view. Whilst she is a vegetarian, she scoffs chocolate and ice cream as if each time will be her last and won't go near a gym as she detests fitness.
She does however, stay out of the sun and she rarely drinks alcohol. She consumes water by the gallon and sleeps like Rip Van Winkle. Allied to a very good metabolism, these four things she says are the reason for her amazing complexion.
