You'd better, if you want to pass the HGFA exam for an advanced rating (paragliding or hanggliding). I found this quite amusing.
Me not being of the smoking persuasion, the two questions on this topic were pure guesswork. Still I made the theory exam (learned a lot during studying for it) and will need to complete only some more minor check flight stuff to finally acquire the advanced rating. That'll allow me to fly XC in Austria later this year.
In the meantime I've passed the 100 hours airtime mark, and had some nice flights (local only due to the weather) over the weekend.
