Mundance vs Routine

They say, when a man is near death, he loses interest in mundance affairs. Most of us tend to say this" its my life and I guess I have to go like this..." and this sounds to me like life is difficult and we have no choice at all...No wrong and right here cos life keeps going and our feelings to life will not change a thing here. I am sure even if we know we are not dying, but we will still feel dull in certain time and lose interest in many things. But well, what is so called mundance affairs here??? to me, mundance is something that makes you helpless and dull. When I was in school, school assembly was the mundance affairs.. it was so annoying that we all had to stand still in front of those selected prefect and sang the national anthem and school song. We had to put up our hand and take oaths( in adult's eyes, it is always good to say something like that, but in my mind, I was just hoping to end that soonest!).
My current life is kind of Routine too, go to work and go home, go out and go home... I repeat this again and again but it is not about how many times or how long time I gonnna do the same thing, it is more on the feeling that make me feel stable. Everything is simple and ordinary but the most important thing here is the feeling of security.
