Why do we remember our first kiss but not our tenth? What determines what we remember and what we forget? Memory is quite economical.

We shower, brush our teeth, drink coffee, commute to work, do our jobs, eat lunch, commute home, eat dinner, watch TV, spend too much time on social media, and go to bed.
