Thinking is overrated.
Most people don't even use their brains. Recklessness prevails. Mindless actions and decisions, without any consideration of potential consequences. Behaviour patterns that are being adopted and demonstrated just because it is the norm. People love to blindly follow without questioning anything! How on Earth do they do that?
I've always been hardheaded , interested in practical considerations and reasoning. I can't just accept what you told me just because you told me. I need reasoning and proof. I need evidence. I can't just believe anything I'm told without any credible explanation or information backing those claims being made. Maybe I'm too suspicious of a person and life would be a lot more fun if I was absolutely mindless, but still, I would pick sad over stupid any day of the week.
Suspicion doesn't make me smart. It does, however, motivate me to do research and gather information before jumping to conclusions and this process does make one a bit smarter. It is like a brain workout. Like studying maths for instance. You probably never used calculus in real life unless you are an engineer, however it still helped you develop your mental strength and capabilites and it definitely made you a better problem solver in real life's hardships.
Our brain represents 2% of our body's total mass, yet it consumes about 75% of the body's energy and nutrition resources. It is the most important part of our body and it is safe to say that our skeleton and organs where made just to sustain and protect our spine and brain. Maybe that would explain why most humans refuse to use their brains; to ensure its safety given its importance.
Thank you for your attention
