Lets face it. Americans are lazy and fat. 42% are obese. Things like this contribute, but people have to take responsibility. Get off the iPhone, get out and walk. Thinking deeper, socially, about the subject, I remember how the shopping malls helped form me as a teenager. I had a lot of fun there. We had three malls within 10 miles. Its here I shopped, ate, made friends, met girls, and got exercise. As a latchkey kid, I had to develop social skills. A lot of young men now struggle with lonliness and relationships because they never venture out of their room or house. I personally know several young, single men who've shared this with me. Its become the norm to live life via online and makes it hard to meet girls and friends.
