Penny for your thoughts?

Lol after studying in the library for so long i've realised that medicine students(yes only medicine students, i dont see dentistry or pharmaco students doing this) have this tendency to study, then for a brief moment stare into empty space, as if in deep thought, and then return to their studying.

I guess "staring into empty space" is the point in time where you try to run events through your mind...... like how alkalosis causes Hydrogen ions to move out of cells and potassium ions to move into cells resulting in hypokalemia etc.......

But sometimes you gotta wonder what people are really thinking about..

1) "wah shit man im damn hungry......" (u noe who u are=p)

2) "that girl sitting over there at the next table is really really damn chio man........sighz....."

3) "Perth............" (replace country with holiday destination of choice)

4) "i hope the shut-up ang moh woman doesnt come today......."

5) "what drink should i buy from the 20cent machine today?"

6) "who is tuck, who is som and who is bong???"=p

7) "shit man die liao lah.... cannot finish studying....."

8) "if i study hard and become damn smart all the chiobus will flock to me to ask me questions...... just like Moses......"

9) "basket people think that im staring into space but actually its because ive got a stiff neck...."
