I gave a few lectures at the local senior center. We focused on basic lung health, simple respiratory exercises and general topics to do with encouraging better breathing by lowering allergen content (or at least being aware of allergens in our daily lives). They all went over very well and the participants had fun (it helps to have a raffle, too!)
While I haven't been able to do that in a while, I have some fond memories, including getting over mike fright. After all, a room full of seniors who are waiting for the bus and want to know if they won the raffle can be a tough crowd.
