The provided texts from "Wanderlust Over 70" explore the concept and significance of collecting travel mementos. The first source, "Why I Still Collect Mementos (and Why You Might Too)," examines the personal reasons behind keeping souvenirs, highlighting their role as memory aids, gifts, and part of a travel ritual, while also cautioning against the pitfalls of clutter and unintentional collecting.

Its follow-up, "A Map of My Life, One Souvenir at a Time," further discusses common items tourists collect, both intentionally and accidentally, and introduces the innovative idea of blending tangible souvenirs with digital companions to enhance memory preservation.

Both pieces share the perspective of an author who embraces mindful collecting as a way to enrich and recall travel experiences.
