I'm very excited, since I'm going to the old folks home for my second lecture. The first was very well received. This is a tough audience, since half of them fall asleep! As a tribute to Bollywood, I keep a very high energy production going. I only use a few slides.
My big number will be 'Dance of the Plates', where two people do naughty things with seat cushions. I only keep this up for 30 minutes, and then there are questions. So, I'm a star of radio and stage. If somebody videoed it, then my credentials would expand! :)
