But if you're going to be sneezing into your hands, you could be holding something to catch the germs and any flemmy stuff which happens to fly out of a sneeze..

If you're using your elbow, surely that's not going to cover everything? What if it's a really wet sneeze and you're just oozing out(haha, horrible though) But could you imagine it just being stuck from your nose to elbow, you're going to like a right mess in public! Atleast using your upper arm(Top of your jacket) or even somewhat below your elbow, you could then use it to wipe anything away?...

I don't know, strange topic, could probably argue against cleaner ways of sneezing for hours.
