There is nothing permanent or changeless in this world. Time influences everything and everyone. We don’t usually pay attention to things changing as it happens so slowly, but some changes are really surprising.

Bright Side brings you some pictures of unbelievable examples of time’s work on things and people. Look through them to the end to get to know what time can do in a few months and over hundreds of years.

1. These are the footprints of a monk made by him praying in the same spot for decades.

2. Here’s 6 months worth of buildup in a pipe used for a mineral pool spa.

3. This entire brick wall has been shaped by the sea.

4. Hands across the generations

5. Before and after powerwashing. New York used to be a much dirtier city back when the Northeast ran on coal plants.

6. 2 cars were left in the woods many years ago.

7. 2 identical teddy bears. The one on the left has been my brother’s for 30 years; the one on the right has been kept in storage for my brother’s first child who was born today.

8. Ghosts of Union Station

9. An old guitar

14. This can has been sitting in that cup holder for over 2 years.

15. This is the effect of sun damage after 28 years of driving a delivery truck.

16. Worn steps to the top

17. This parking lot used to be some sort of building. Instead of removing the old tile floor, they simply paved over it.

19. This exterior corner next to the front door of the local bike shop shows significant wear from the last 30 years of customers striking it with their pedals.
