Nothing serves as a reminder of our past quite like a photograph- we can see the past come to life in those photographic images we collect in books and desktop folders, and taking a look back can sometimes make you feel quite nostalgiac.
Photographer Ana Oliveira has taken the concept of passing time to a unique place in a series of portraits she calls "Identities," which features older folks posing for updated versions of photos from their younger days.
It's an interesting way to see how the subject's physical appearance and fashion sense have changed over the years, and the images celebrate their lives while embracing the inevitable passage of time.
