Reading about the cardiovascular system is like reading sherlock holmes or watching 柯南, it is astounding how everything makes perfect sense at the end and I am left amazed at the sheer genius of our body. 

The only difference is, I will be tested on this material after the end of the chapter. Haha :) 

That said, I am so so enjoying the material right now, I just wish I had a little more time to learn, absorb and be able to understand how everything we do impacts our big hearts.
