do you know how excited I am ?

Yesterday, I had my biology practical class where we were going to use the sphygmomanometer and stethoscope to measure the blood pressure. I found it rather interesting to test out the stuff because I always wanted so much to use the stethoscope when I was young.

Well, I heard my friend's heart beat ( dup dup , exactly. LOL). The device was not really comforting when you use it. You ears hurt if you using it for longer period of time.

Hehehehe, so I had become so-called doctor for few minutes~~ HHAHHAHA :DD
