This book reminds me of why I got so easily bored during summer vacations, so many years ago. There was no Internet, no Gaming systems, no home PCs, no DVDs or CDs.
So we played board games, card games, sports, and watched hokey shows like "Dark Shadows". We walked on long trips for very little, except to explore what was then a safer world.
I feel the author maybe focused on the wrong choices. For example, the then and now aspects of popcorn. Then: you had regular popcorn, multicolor popcorn or Jiffy Pop. It was all made on the kitchen range, and took more skill than punching buttons on the microwave.
Now: the current youth stands on the technology of several generations. Baby Boomers need to choose "oldfashion", "natural", "movie theatre", "corn on the cob", or a dozen others. But for youth, there is only one method of choice. Take away the microwave many cannot make it. Only those who have asked, (or had great teachers/parents), would know how to use the range to produce popcorn. So youth today feel a microwave is a necessary part of the kitchen, where older family members consider it a luxury. I am not a specialist, but this would create the greatest rift to me, instead of the increase of variety of choices.
