Prior research has suggested that time appears to move faster as one ages. The BPS blog highlights some research pointing the other direction:
Age accounted for four per cent of the variance in how quickly participants said the last ten years had passed and just one per cent of the perception of time's speed in general. By contrast, how busy and rushed people reported feeling accounted for ten per cent of the variance in subjective speed of time. Consistent with this, women reported feeling more rushed than men, on average, and they perceived time to go by more quickly.
Quite why the idea that time speeds up with age is so widely believed requires further study, the researchers said.
