Why do days – and years – shorter when we get older?
The answer is a matter of physics, says Professor Adrian Bejan of Duke University. , published March 18, 2019, in the journal European Review the obvious temporal difference can be blamed on the ever slower rate at which images are obtained and treated by the human brain as the body ages. Bejan said in a statement:
People are often amazed at how much they remember from days that seemed to be forever in their youth, not that their experiences were much deeper or more meaningful, just because they were being treated in rapid fire.
Bejan attributes this fenome n physical changes in the aging human body. He explained that, as tangled tissues of nerves and neurons ̵
1; the basic units of the brain – mature, they grow in size and complexity, leading to longer paths for signals to cross. As these pathways begin to age, they also degrade, giving more resistance to the flow of electrical signals.

These phenomena cause the frequency at which new mental images are acquired and processed to decrease with age. This is evident from how often the children 's eyes move compared to adults, noted Bejan – because children save images faster than adults, their eyes move more often, acquire and integrate more information.
The end result, says Bejan, is because older people look at fewer new images in the same amount of time as it seems that time goes faster. He said:
The human mind feels that time is changing as the perceived images change. Current is different than the past because the mental display has changed, not because someone's watch is ringing. The days seemed to be longer in your youth, because the young mind gets more pictures in one day than the same mind in old age.
Bottom line: Why time seems to go faster as we get older.
