Attention seekers.Seriously, you are right as it is annoying and unnecessary. Bad nerves being a bit jumpy?:)
Well not really, but my blood pressure certainly jumps each time :P
I totally let got when I sneeze. :P I have a fear that if I hold anything back the pressure will cause my head to explode.
On the up side, when I do this I make sure I'm not around anyone (going so far as to get up and run out of the room when I feel a sneeze coming on) because I do realize how annoying it is.
I don't think this guy is merely 'letting go', it's more like he actually starts to yell the half second before he sneezes.
I also like to let go a bit when I sneeze though. I hunch over, and kind of do a little hop right as I sneeze, to get the impression of my sneeze briefly launching me into the air. Naturally I also make sure that nobody is around :P
Sneezing underwater is pretty refreshing as well.
