When does a person start losing thier youthful “isnt-that-precious” look? After 30? 35? well the most is probably 40. And then people point to Demi Moore, is she still precious? Nah, not really. She looks beautiful and graceful but hardly the youthful beauty she once was. But for most people possibly 40 is the limit. 35 is considered the upper limit of youth. I would appreciate anyone reading this would leave thier opinions on what they consider the upper limit of youthful beauty.
