Clean hands? Paper towel please!
Washing hands is something we all do on a daily basis. Whether you are at work, at home or when you are out and about, you are bound to wash your hands at least once in a day - I hope! So, what do you do after you finish washing your hands? Well, you have to dry them of course! We've all been told that bacteria strives on damp surfaces, so we have to dry our hands. Question is how?
Well, according to research you don't need those fancy hand drying machines that you might find in a shopping centre or at work, all you need is disposable paper towels! In fact, paper towels work better than those high-tech hand dyers - be it the traditional ones that blow warm air, or the cool looking and insanely loud Dyson Airblade.
...the use of paper towels consistently out-performed all the other drying techniques, especially with regard to bacteria left on the palms and fingertips. -Snelling, 2010
Not only do paper towels trump everything else, the study conducted by Snelling found that if you rub your hands while drying your hands with the warm-air hand dryers you can actually increase the bacteria count. The Dyson Airblade fares better than the traditional hand dryers at drying your hands and keeping bacteria at bay; but at the end of the day, paper towels are still the most suited for the job.
So next time when you've finished washing your hand, go and grab a paper towel. Or if none are available, look for a Dyson Airblade. If that is not an option either, go for the traditional hand dryer - remember to leave you hands under it for at least 30 seconds and most importantly, don't rub your hands!

#326 - Hot weather makes me feel lazy.
Today was a super hot and humid day in Sydney and I just simply felt like doing nothing at all. The day was indeed a very lazy day, just sat at my desk doing not much at all. In fact halfway through the day I just decided to lie down and sleep, though not much longer afterwards I woke up because it was too hot. Tried googling to see if there was any explanations to why hot weather makes people sleepy or lazy, but unfortunately didn't come up with anything useful other than a random comment on a forum saying "Cold weather makes me sleepy too. Being awake makes me feel sleepy."
10 useful tips to help with research
"Copy from one, it's plagiarism; copy from two, it's research."
Wilson Mizner
Research is probably something that uni students can't escape from - especially if they're doing honours and have to write up a thesis. Well, recently for one of our subjects which is a bit like preparation for thesis, we needed to write a research proposal. While searching through the Internet for credible sources, I discovered (or got told) a few tips and felt it would be a good idea to share them. So here are my 10 tips to hopefully make research a less stressful task!
