I've realised that after writing exams, some days after the examination we tend to get nervous and anxious about our performance during the examination, even when we are sure of what we wrote, the nervousness still remains until we see the result.
I have also realised that when we go for a medical test eg HIV test, we know we are not living a reckless life(i mean we play safe), we still get nervous about the result of test.
WHY? Pls answer me because this is not a rhetorical question!!!!!!!!!!!!!
