It's the rise of dependence on the internet and the social interactions there along with the decline of respectable news gathering organizations that have crossed the line into fronts for advertising. A decline in truth.
I find that the more I avoid television, radio and the internet, the better I feel because the people in the real world around me aren't discussing wars, politicians, murders and suicides. We're talking sports and good food and, today, vacations I'm going on.
These things don't make me sad. The internet, television and radio make me sad. So I avoid them altogether.
