after 3 yrs of exposure to laboratory work, it's hard not to be paranoid over airborne germs; bacteria, yeast, fungus and all others. there is a tendancy to visualize movement of organisms everytime. Occupational paranoia, you can call it.
if i see someone sneezing just infront of me, i can almost visualise the particles travelling through the air and then landing on myself. closing your mouth at the point of sneezing is not good enough actually, the particles would have already flown over to the end of the room, even before your reflex to close the mouth. Hence, it really isn't that necessary to close your mouth when sneezing. It doesnt help really. Manners yup, other than that it's really useless. lol.
after this particular prac on microbiology [back in SG; where we actually tested chicken rice for bacteria], we spread the grinded chicken rice over culture dishes and left them to incubate overnight.
results: we actually had colonies growing the culture, bits of them, not those full colonies.
conclusion: there are bacteria on chicken rice from FC2. haha.
basically lah, its hard to be totally rid of bacteria. they are everywhere.
happy breathing bacteria. cheers.
It seems that we have to wash our hands with soap for a certain period of time ie. the length of happybirthday to you song.. And... guess what?
THERE WOULD STILL BE THOUSANDS AND MILLIONS OF BACTERIA [ although it's lesser than before ] :P
last entry. haha.
anna: it doesnt really. lol.
spyda: some of them bacteria are actually essential for mantaining proper bodily functioning. hee hee
xiaobudianz: i'm a very paranoid person in general. haha. think too much lah.
