This gives you plenty to think about. In the U.S., mainstream media has characterized Tyson's responses as "harsh" or "odd." However, I believe he was simply being honest, perhaps even offering a nugget of wisdom to the interviewer.
Earlier in my writing career, as I worked on books, the idea of legacy was always on my mind. Without biological children of my own, I viewed my words as my legacy, which fueled my motivation to create. Now, at fifty-three, I’ve come to understand that for many of us, the only enduring legacy we leave is the way our lives influence others—for better or for worse.
Sometimes I wonder looking at a person going through a rubbish bin for bottles to return, what happened in their life to end up that way. I also think what kind of impact it has on their family. Yet, perhaps it is actually better for the family at times that someone drifts away.
I wonder sometimes too. I think sometimes the pressures of life are too great for people and something inside them breaks. Also, maybe they realize the damage they're doing by being around their family/friends? Homelessness would have it's own subset of stresses but, perhaps, some prefer the struggle for daily survival over the stresses of modern day life? I'm not sure.
