In today's world it is not uncommon to see hypochondriacs crawl out of the woodwork when the word "pandemic" is uttered. As magicians we need to be aware of these strange goings on and be able to adapt. So many people are afraid to touch ANYTHING that might have come in contact with your mouth or even your person in NORMAL times.
So when some crazy flu goes rampaging across the world, we need to maybe look at a few of our handlings of tricks and make sure we remove, what we might feel, is the simplest of things.
Putting a card in your teeth during an ambitious card routine, placing a borrowed object into a phone, licking a spectators forehead to stick a card to it. (I hope I am kidding about that last one by the way) These things and more need to be considered so those helping us out can get the full enjoyment without worrying we are going to give them the plague.
Of course if you want to have some real fun, remind them that we use the same glasses and silverware EVERYONE else uses in a restaurant and watch their eyes widen.
Ah good clean family fun.
