It's an indisputable fact that our faces will have changed quite a bit by the time we're old, and if we're lucky enough to live to 100 we wil look virtually unrecognizable compared to our younger selves.
But how much do our faces actually change as we reach ultimate old age?
These incredible photos are part of the "Faces Of Century" series by photographer Jan Langer- a side-by-side comparison of how people who have lived for a century look now compared to how they looked in early adulthood.
The twelve people Jan chose as his subjects were all chosen from his homeland, a dozen people representing the over 1200 centenarians who currently call the Czech Republic home:
Photographs show portraits of one hundred years old Czechs. Nowadays, there are over 1200. In fifty years their number will reach 14,000. How these people see their life after such a period? The majority of those I approached agree that with advancing age life is faster; until, at last, the life will pass in a moment. Time is shrinking, as are the faces of the elders. I wondered what changes and what remains on a human face and in a human mind in such a long time, and in such a short while in relative terms. I wondered how much loneliness of the old age weighs, and what memories stay in 100-year-old mind
