Ha John 1652 - your comment made me laugh. No I don't suddenly grab a kleenex or my phone while I'm driving, not that I could even hear my phone with my jardine!!

Plus, have you ever tried to blow your nose with a FF helmet and glasses on? I find it very awkward. Oh and before you ask: yes, I do lift the visor beforehand - lol.
I also notice that when I'm almost at work (an hour a way) is when my nose will suddenly start to run - how inconvenient is that!!!
