Crazy Aircraft #69 – A human powered ornithopter takes to the air
by Marshall Brain | September 23, 2010

The technique known as CPR (Cardio Pulmonary Resuscitation) has saved thousands of lives since it was invented and promoted several decades ago. Millions of people have gone through training classes with the Red Cross and other organizations. But CPR is now getting a facelift, and it no longer requires formal training.

And worms:
How to start your own worm farm -or- how to compost your kitchen waste with worms
But what about honeybees? The reason this question came to mind is that I built a little garden in the Brain backyard, and I planted cantaloupes and pumpkins (plus some other stuff, but Trixie dug almost all of it up).
