How can I answer this without being political? I feel that the two sentences I quoted are wrong. No wars? I was aware of many wars growing up and in my early adult years. Assassinations? There were some, and many unsuccessful attempts. Social upheaval? Well, staying out of politics, we are the computer generations. The first generation for computers to be affordable to most people, and not take up entire floors of buildings.
Writing this I think that maybe my generation has been defined by upheaval. We don't have the major midlife crises that result in trophy spouses and Harley motorcycles in the garages because we never had time to become comfortable and stagnant. Life: job market, economy, technology, etc. changes so fast that we are always adjusting.
As to how I'm entering the later 40's and 50's, the same as before, rapidly adjusting my plans and goals to the world around me.
