Why does time fly as we age?

Do you ever feel that childhood lasted forever while the years of adulthood seem to pass in the blink of an eye?

Scientists say time itself does not speed up as we age. Instead the way our brain experiences and remembers time may change. Researchers have suggested several possible reasons for this feeling including our age daily routines memories emotions and changes in brain activity.

The brain experiences time differently

Clock time moves at the same speed but our minds do not always experience it in the same way. One explanation is known as the proportional theory. For example when a child is 10, one year represents about 10% of their life. At age 50, one year represents only about 2% of their life.

This may make each new year feel shorter compared with the amount of life already experienced.

Fewer new experiences

Childhood is often filled with new people places activities and experiences.  These moments can create many distinct memories.

As people get older daily life may become more routine. When days and weeks follow similar patterns fewer events stand out in memory.  Looking back an entire period can therefore seem as if it passed very quickly.

When routine takes iver

Another possible factor is attention. During familiar tasks the brain can work almost automatically leaving less attention focused on the passing of time. As a result hours may seem to disappear while we are busy with work household tasks or other regular activities.

Emotions can shape our memories

Strong emotions such as excitement happiness fear or surprise can create vivid memories. In contrast days filled with boredom tiredness stress or repeated routines may blend together.

When fewer moments stand out the past can feel shorter when we look back at it.

What does dopamine have to do with it?

Dopamine is a chemical messenger in the brain involved in motivation reward and several other brain functions. It has also been linked to how people perceive time.

Changes in dopamine levels and brain processes as we age may play a role in how quickly or slowly time seems to pass.

Can we make time feel fuller?

We cannot actually slow down the clock but experts suggest that new experiences may make life feel more memorable.

Trying different activities exploring new places learning new things and taking part in creative experiences can create more distinct memories.

In this way the feeling that time speeds up with age may be connected not to the clock but to how the brain processes attention emotions memories and everyday experiences.
