Carl Sagan also predicted we were going into another ice age. This was back in 1979 and I watched him religiously on PBS.
While I can't speak for other people, I can say I do believe in astrology and I can tell when the Moon shifts into my natal placement which is in Aries. I become impatient, antsy, argumentative, confrontational, and hyper critical of others if they are doing something to irritate me. Aries mooners have two moods, ecstacy, and suicide. You have to teach yourself over time that a bad day is just a bad day, not the end of the world and by the same token you have to learn to digest the fact that winning streaks will end. But it's still a difficult placement to live with. We are saved by the fact that we are cuddly, fun and just plain irresistible.

And of course, humble.
I said yesterday would be a challenging day because of the Mars - Pluto opposition combined with the Aries moon. I was open minded about the day and hoped I could eek through without catastrophe. I took my mom to the grocery store. It's hot here.
Over ninety degrees F and mom felt a little sick. When I took her home her apartment building was on fire! I kid you not. There were three fire trucks and a fourth almost blocked me in at the parking lot. Mom took her bag of groceries and got out of the car. I told her to come back to my place. It's cool with the ac on and she can't stay go into a burning building anyway.
She started yelling and screaming at me to leave and I just said to myself WTF, I have had it! So I left. She's OK, thank God, but her apartment suffered serious water damage and many of her possessions will have to be replaced. I knew it could be a really bad day. It was.
I said yesterday I wouldn't give my sun sign til today cuz I knew yesterday was a danger zone.
My Sun sign and ASC are Taurus. I'm one of the nicest people you could ever wish to meet, but I do have limits.
