It's easy to see the physical changes as we age - but what about the mental changes?  We know adults have a greater capacity for reason than children, we know seniors may be more forgetful than teenagers...but what about time?  It turns out that, when we age, how we perceive time changes, too.   This audio clip and accompanying article from NPR explains a few theories why.

Need to take a deeper dive into the science behind this phenomenon? Try a reprint of W. H. Meck's article "Neuropsychology of timing and time perception," from the journal of Brain and Cognition, available from the ATH store.
