Kiss, car, concert -- one of the joys in life is the first time we get to experience memorable moments.

We all remember them. They stay with us in our rolodex of memories, tucked away to bring a smile to our face, even if they didn't necessarily go according to plan.

And while we all go through these milestones, there is the question of when we should. When is the proper age to wear makeup? Attend a sleepover? Get a car? Opinions differ, which is why a new Harris poll surveyed nearly 2,500 adults and 500 teens to get their takes on what the appropriate age is to do a wide variety of things, from owning a pet to going on a date to seeing an R-rated movie. So, take a gander and decide for yourself whether you agree.
