One never sees or hears anyone hiccupping or sneezing on live television question and answer programmes? I don't remember anyone getting hiccups or sneezing when asking or answering a question.
do you want them to then ? if you are going to sneeze take your index finger and rub it slowly up and down the back of your neck, the sneeze will stop midstream, don't know why but it works, my grandma told me about this.
