This is nothing really to do with your point, I know, but I just wanted to quote you out of context because the words work for what I'm about to say

...
It occurred to me today, while spending ages looking for the Vitamin D tablets in Tesco and a whole barrage of people shuffled past me coughing and sneezing proudly into the air as if it was some form of self-expression, that if people actually made the effort to try to stop spreading this stuff, quite literally hundreds of thousands of people around the world may actually live for another year.
There's no perfect solution. Putting your hand over your mouth isn't great because you then touch stuff, but it's better than nothing and goes some way to demonstrating you are a higher life form with an understanding of the universe rather than a farmyard animal.
I've developed a habit of sneezing / coughing into my arm, the flexible joint thing where the top bit connects to the bottom bit and has an elbow on the other side, I'm pretty sure it must have a name. That's not likely to come into contact with much. And I always turn away to do it if I'm near people or food.
I'm not sure if this sounds like a rant, but that is what I'm trying for!
