I like the Bowling alone analogy. I worked in a Military Bowling Center from 1984 until 2001, and watched the interest in Bowling in leagues dissipate as more entertainment avenues became available at home.
It wasn't just limited to Bowling, but also other recreational activities throughtout the community at the time. Parks use to be full of adult softball teams and adult tennis players. Now they are frequented by small family units. Many golf courses have closed in the area. Recreation is becoming a solitary pursuit, that often is done within the confines of the home.
The thing I noticed about Bowling Leagues and recreation, is the social component created many smiles, produced laughter, and created social connections that lasted for decades.
What is left now, as far as the major life activities with face to face interaction. School, Work, Church, and Bars. For many people it is just work, and the complexity of the workplace today doesn't allow for the interaction that it did 30 years ago.
Kid's still join soccer teams, and sports teams, but adults don't play together (face to face) nearly as much as they did before "home entertainment".
I also found Multiculturism interesting. When I was growing up in the 60's and 70's one person could almost completely wrap their arms around the major cultural activities in the country.
Entertainment was limited enough where people were watching the same things on TV, and at the theater, listening to the same limited news events, driving a limited number of American cars, listening to a handful of music genre's, and participating in the same recreational activities.
Now one can be immersed not only in the complexity of modern day culture, but become immersed in the culture of decades past through digital media.
More people than ever are on a totally different page in life. It wasn't always like this.
The blog is amusing but the Asperger analogy is a little inappropriate I think, in a resource like psychology today. Particularly the masturbation comment.
