I learned something new today:  Most of the memories that we can easily recall tend to occur between the ages of 15 to 30.  This is because the brain favors new and novel things rather than the routine and mundane.  By the time we hit our 40s and 50s, first experiences and novelty tend to be less frequent.  This is one of the reasons why as we get older, the time seems to fly by more quickly.

To hedge against this, Meik Wiking tells Brett McKay that we should continue to seek out new and novel experiences throughout life.  This will create more memories and slow the perceived passage of time.
