Am I Doing Something - about it.....?

A topic i had wanted to write on since i saw 'phir milenge'..(when i saw 'philadelphia', i wasnt blogging)....
for a long time, i had maintained that awareness kills fear..the child's fear of the dark, for example - once it realises that there is nothing in the dark that causes harm, it loses the fear.although there are a lot of things which dont fall under this categorisation, those, i believe,are things that we dont have complete info about..
AIDS - a phenomenon that is perhaps mankind's greatest threat ever, because even awareness isnot moving people away from its most usual modes of transmission, and it can strike you by no fault of yours - blood transfusion, infected syringes, certain organ transplants etc. but, it definitely cannot be transmitted by borrowing clothes from an HIV person, sharing of utensils, drinking from the same glass with the person with HIV/AIDS, shaking of hands, embracing,or even kissing an infected person.... yes, i know all of this, all of us who are aware of the disease know this...
but inspite of this awareness, i am not sure if i could bring myself to share clothes with an HIV infected person, to hug him, to maybe even sit close to him ..
it is certainly not lack of awareness thats causing this fear.. is it because i am also aware ofmy mortality but unaware of what lies ahead of me after death? will it take that awareness to get over a fear of something i know about? i, for one,hope not, and the day i get over this fear, i will be a happy man....
