My father is one of them who believe it's a good number, it really cost me many times, I had a room in Australia, I stubbornly gave it away just because the room is #13 and even called a priest to bless it when it's unnecessary. Damn, that's terrible of me!
Take precaution which I ended up losing the room and almost have no place to stay for 2 days. Stranded as well! Let's just say I don't want to talk about it, my arrogance and pride inside me really swallow me alive. Computers don't need mistakes but they do crash when they don't know what to do. But us, we make mistakes but don't crush. Speaking of that, do you believe the scientists' claims that our brain is more powerful than a supercomputer? In theory, yes, but literally and in real life, you think about it, surely it's busted when our computers, even a simple laptop or tablet is a lot smarter than our brains anyways.
I see but I didn't take much notice of it though, I just act it like a normal thing XD I think the theory might be true cos I remember scientist explain that we didn't fully use all of our brain capacity in life, the normal that we used our brain is around 20%.
