Family vacations have changed, but they're still an adventure

I remember taking lots of road trips when I was a kid vacation was another word for work travel, but I didn't mind. I'll never forget flying on a plane with my mom. I wonder if my kids will feel the same. - photo by Amy Choate-Nielsen
The first time I flew on a plane, it was an adventure.

I remember sitting with my mother as we ordered orange juice and a sweet roll, and watched the tiny trees and hills fly under my window. I was thrilled with the novelty of sky food, and I tried to make it last as long as possible with the tiniest bites and smallest sips. I dont remember where we were going, or where we came from, but I remember the food and the patchwork sight of the Earth from 5 miles high.

There was no fear, only excitement and wonder at this new experience.

For the most part, when I was little, family vacations were a land voyage in my parents blue VW Vanagon for my fathers work. We drove from Oklahoma to Washington, D.C., and sometimes Florida, and then back. It all depended on where my dads military duty was for that summer. Wherever it was, there we would go, all together, on vacation.

My parents were efficient travelers. My mother bought a bin full of toys for each of the kids, and we slid them underneath our seats early in the morning when the sky was still dark and my parents were ready to roll. We brought our pillows, and somehow, we all went back to sleep as soon as we started driving.

I dont remember stopping much, although we must have. I do remember that there was a little stool set up with a trash bag inside the van for any little kids with little bladders. I thought it was the most normal thing in the world to balance on a teetering port-a-potty as the countryside zipped by.

My kids would never go for that.

My kids never go back to sleep if I wake them up early for a road trip. They wouldnt let me keep the contents of their bins a secret even if I tried.

In this day and age, theyd never be out of their seats in the car. Theyd be buckled in, and not just buckled, but buckled in the correct, age-appropriate restraint approved by the National Highway Traffic Safety Administration. They have hand-held computer games, headphones, tablets and DVD players built into the ceiling to entertain themselves.

We usually go somewhere fairly close for our family vacations. We like Teton National Park. We like southern Utah. Well head to Oregon or California about once every five years. Last year, we camped in Glacier National Park and fretted over the bears.

This year, we are headed to The Last Frontier, land of the Northern Lights, home of 17 of the 20 highest peaks the United States Alaska (see alaska.gov).

In 2010, the total population of the nations largest state was 710,231, according to the U.S. Census Bureau. In its 663,300 square miles a land span thats bigger than Texas, California and Montana combined youd find about one person per square mile (see alaska.gov). About 98 percent of the U.S. grizzly bear (or brown bear) population resides in Alaska, to the tune of 30,000 bears, according to the Alaska Department of Fish and Game and the National Parks Service.

This trip will be the first time my children have flown on an airplane.

This time, along with the excitement and wonder I feel, I am afraid.

I know more now. And much like road trips of the 1980s followed different rules, I know now that times have changed. I know my sons meltdown could be filmed and plugged onto Instagram. I know our experiences could be on the evening news.

So many things could happen, I know. Ive been packing and re-packing for weeks, making lists, gathering snacks and books, to try to prepare for all of those things that could happen. Part of me wishes I was back in the good ol' days, when someone else made me a treasure bin and bought my orange juice and sweet roll and told me everything would be all right.

Thats my job now.

Cross your fingers kids, were going on an adventure.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
