My Heart Is An Engine
I realized I learnt quite a lot during the last week of Maintenance course. It is very boring, I admit, but I managed to learn some Physics from my mechanic instructor. Haha...learn Physics in army. He made me ashamed, because I thought mechanics have low education (nothing wrong with that...just a biased generalisation), and instead he proved me wrong, because he has quite a good grasp of physical concepts. Thus he not only showed us how to do, but he even understood the way Physics work in those vehicle parts. And best of all, he has a wide range of knowledge in many other areas which are related to his work. Can you say 'all-rounded'?
Thus I kept turning to my friend and said 'Woah...physics...' whenever he explained physical concepts. When he told us about the dynamics of oil prices, I turned and said 'Economics.' When he told us the history of armoured vehicles, I murmured 'History.' And he knew almost anything! I think I had said 'Marketing', 'Chemistry', 'Current Affairs' and even 'Business' at the end of the day.
And one part which really quite amazed me was the part where he described about how the engine worked. Ok, I still don't get it. I am going to do engineering and I don't know anything about engines. The engine is really a complicated mix of many machine parts which work together accurately and efficiently. I have no idea how many years of research and design it took before those geniuses made this complicated thing. And then I thought of those pistons, and those air. And I likened them to arteries and veins, and blood, and I realized that...
My heart is an engine! And it runs by itself! What's that biological term again? I forgot. (I have forgotten a lot of things since I wore the green uniform. Maybe they are right - it makes you stupid.) I remember how I used to write 'The heartbeat is initiated by the heart itself' in my Biology essays. That's amazing. And even if it was stimulated by, say, the central nervous system, still it requires none of our will to make it work! It requires none of our effort to make it work! When was the first time you realized you had a heart? 3 years old? Maybe later? Well, my heart has already been beating even before I knew I had one.
The heart must be the best engine ever made. It can last like, 60, 70 years on average, probably even up to a hundred and beyond, and you don't have to lubricate it, or change any elements every 24 months, or every 40,000 km, as you would in a Land Rover.

Ok, so I anticipate someone might say I have a very automatic and physical concept of the heart. It beats and pumps blood to the rest of the body and the lungs. I apologize to the poets out there who thinks that the heart is a symbol for love, to the writers out there who thinks the heart signifies desire, but pardon this scientist who thinks it is a wonderfully made...uh, engine.
P.S: New insight. I realized our body also has an inbuilt cooling system. How cool is that!?
