Greg Foot's video: What actually is ALS The SCIENCE Greg s icebucketchallenge

Another in your news feed? Why yes, yes it is. However, before I got down to chucking some very cold water over my head I wanted to give you my take on WHAT actually is ALS and WHY I think it's worth keeping this going. Cheers Brett Walton, Mike Houston, Steve Mould, & Dave Cornthwaite for the challenge. I pass it on to Joseph Burfitt in Seattle, Richard Bray down under, and Charlotte Willis in London. Enjoy!
