Misty Colored Memories Of The Way We Were

I was inspired to write this post from another post I read on Kim Griffin’s Blog about Time Travel. I had prejudiced my idea of what the post was going to be about (before reading it) – science fiction and time travel. To my surprise it was about neither. The post centered around music. More to the point is how hearing a song can BOOM; instantly transport us to another time and place.

Her subject was music however mine is smell. For me, sometimes the smell of an apple pie baking transports me back to my childhood days when I used to spend weeks at my grandparents house. On occasion during a few summer days when I drive past honeysuckle plants and smell their nectar, I am transported to that summer when the 17 year old girl sent to watch her cousins or nieces gave me at ten years old my lessons in French kissing.

The combination of cigarette smoke and hospital rooms transports me to my aunt’s hospital bedside when the decision was put forth to family members about not feeding her anymore because feeding her was just feeding her cancer cells and bringing death on a little quicker.

The olfactory bulb (group of nerves that enable our sense of smell) is closely related to our Limbic system which is made up of the Hippocampus and the Hypothalamus among other parts of the brain. The Limbic system is primarily responsible for our emotions, and the formation of memories. Being in such close proximity to the olfactory bulb, is it any wonder that smells can trigger such strong memories?

Do you have any smells that can transport you to places? Are they good places or bad places?

Amazing Scientific Facts


Amazing Scientific Facts

I’ve always been somewhat of a science freak. Not the kind that would be seen in a laboratory but I’ve been fascinated with our wonderful world and the macro and micro universe. I just found out that we call our ‘world’, the universe because it means one sentence (“In the beginning God created the heavens and the earth.”). Anyway, the planets, sharks, thunderstorms all caught my attention when I was a kid.

I thought I might share with you guys some of the facts that science has learned me. I know, I said learned on purpose. I meant taught. Have fun with this. I promise, no test. Feel free to add anything you know that I have left off.
