Time ticks for smokers who quit
People who try to give up smoking may experience a slower sense of time passing, according to a study.
Researchers in the United States have found evidence to suggest that people who attempt to kick the habit lose their perception of time.
The phenomenon may be linked to the effects of nicotine withdrawal on the brain.
The researchers believe it may also contribute to the loss of concentration and increased levels of stress many people who try to quit experience.
Dr Laura Cousino Klein and colleagues at Pennsylvania State University based their findings on a study of 42 men and women - 20 daily smokers and 22 non-smokers.
They asked all of the participants to estimate the duration of a 45 second period of time.
