Yo...Today i feel better d...How about Nicholas? Today we did bio experiment in class.... so excited...XD We separated into two groups... My group drank plain water while the other group drank coffee(no sugar/milk)... I suppose in the group that have to drink coffee but i dun like coffee so i shift to another group.....Haha.... So bad la me....

The experiment is about caffeine and heart rate... We have to check our pulse after drinking the coffee/water....
