Time flies when you’re having fun. As an old timer, I have responded countless times that “Time flies even when you’re not having fun.” So I was most gratified to find this research on exactly that.

A Duke University researcher has a new explanation for why those endless days of childhood seemed to last so much longer than they do now–physics.

According to Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke, this apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are obtained and processed by the human brain as the body ages.

The end result is that, because older people are viewing fewer new images in the same amount of actual time, it seems to them as though time is passing more quickly. 

The theory was published online on March 18 in the journal European Review. Continue reading
