The other day I was watching 60 minutes and they re-aired a clip that they had done a couple years back. It was about Forrest Bird, the inventor of the Bird respirator. Bird is now 88 years old, and is still enjoying life flying his planes and working long days. He first invented a makeshift respirator for his friend who had trouble breathing. Soon, he was trying to find a way to make an affordable, portable respirator for anyone to use. He has saved millions of lives. If you'd like to watch the video clip from 60 minutes, click here. I encourage you to take the time to watch it. It is very good.
