So, eye opening to see how consistently, no matter what, over decades (my biological father is almost 80 years old and my biological paternal grandfather was about 55 years older than me and his father got close to 100 years)human behavior has not changed and then I remember well evolution takes time and if the human spark occurred 50,000? years ago, we have a long way to go and are there any 'geniuses' who think that this current Earth environment is going to hold out for us to get there? I actually worry about people because every once in a while I see an article about really poor air quality and it is no wonder some people are wearing masks to cover mouths, noses and even eyes.
