If I understood the article properly, then:

PLAY - Playing a physical game like tag, catch, soccer, volley ball, hide and seek... provides both physical exercise and cognitive / social stimulation because of group play's dynamic nature.

This next bit might not be useful. In college, the distance from my apartment to school was 15 - 20 minutes. And I took to the habit of listening to audio books on my ride (traffic was low so it was relatively safe).

I noticed that if I listened to a track while riding, I would remember exactly where I was the next time I listened to the track.

(The track reminded me of the location, rather than the location reminded me of the track.)
