I’ve been thinking about a forensic investigation technique lately—and not just because I like reading mysteries. No, it’s because I recently came across Dr. Edmond Locard’s principle of exchange, which states, “Every contact leaves a trace.” This principle is the basis of forensic science—trace evidence, such as fingerprints, DNA, footprints, or fibers, can now be used to link people or objects to crime scenes.

Every contact does leave a trace, and not just forensically speaking. The people around us, and what we allow into our surroundings and our minds, leave traces on us and in us. We all have people in our lives who inspire, energize, and encourage us, and thank goodness for them. We probably also know people who drain us of energy or leave us anxious and irritated after every encounter. To protect our happiness and overall mental state, we can seek out the people and things which lift us up, while minimizing contact with the people and things which leave a negative trace.

I try to walk the line between hiding from the legitimate problems in the world and allowing them too much space in my head. I know what I choose to read and to watch leaves a trace, so I don’t choose to read or watch certain things, no matter how worthy they might be. I surround myself as much as is in my power with things I want to leave a trace on my world. My office especially is a place that holds symbols and talismans of inspiration, as well as reminders of love others have shown me, and things I aspire to.  I’m also fortunate enough to have a great deal of control over the people I interact with, and therefore most of them leave positive traces.

What about the traces we ourselves are leaving? It bears remembering that we have the power to influence others with our words and actions.  After all, happiness is contagious.

With every interaction, we touch others and they touch us. What kind of trace will you leave?

Every now and then, instead of all the suffering, problems, irritations and frustrations of life, I see some things that fill me with wonder. I hear a story about something amazing or inspirational or beautiful. I marvel at the creativity and determination and sheer joyous spirit some people have. I’d like to share a few of my more recent discoveries in this post.

An anonymous someone has left a number of intricate paper sculptures carved from books at various libraries, museums and festivals in Scotland, beginning with the Scottish Poetry Library. (Click here for the whole story and photos of the amazing pieces.) Each piece was accompanied by a tag with a short message. Here is the wording of the one found at the Scottish Storytelling Centre, of a dragon in a nest: “A gift in support of libraries, books, works, ideas…. Once upon a time there was a book and in the book was a nest and in the nest was an egg and in the egg was a dragon and in the dragon was a story….” I would go to Scotland just to see these wonder-full creations!

This inspiring video (thanks to my husband who sent the link to me) demonstrates the power of belief and persistence. It’s also a pretty good advertisement for yoga!

Imagine that you’re blind. You’ve created a system using elastic bands, to enable yourself to write in longhand the novel that’s brewing in your brain. You complete 26 pages and begin to think about finding a publisher. Then your son comes to visit and breaks the bad news: your pen had run out of ink. Your pages are blank. What happens next is the wonder-full part: using a special police technique that involved shining light on the paper from various angles to reveal the indentations made by the pen, Dorset County (England) forensic service expert Kerry Savage was able to recover the entire manuscript except for one line. Ms. Savage spent five months of lunch breaks working on the project, in addition to her regular job helping to solve cases of murder, fraud or arson. Click here for the whole story.

Scientists in a new field known as “soundscape ecology” are using radio telescopes to record extended stretches of audio in wilderness areas. They’re studying the sounds found in entire ecosystems, and the effects humans’ sounds have on nature, among other things. While this is interesting, what I found wonder-full in this article was the links to short recordings of sounds found at Denali National Park and Preserve, such as “Alpine stream feeding into an ice cave,” or “Bear with cubs.” Sitting here in Florida, I can listen to nature sounds from Alaska!

I hope you’ve enjoyed these stories—and I’d love to hear from you if you have wonder-full stories of your own. Have a wonder-full weekend!
