The Coming Neurological Epidemic

Interesting 4 minute TED talk by Gregory Petsko.

Three things I didn't know:
1) By 2050, there will be 31.6 million Americans over the age of 80 and if we don't do anything about it, 1/2 of them will have Alzheimer's disease and another 3 million will have Parkinson's disease.
2) People with neurological diseases have a low incidence of most cancers.
3) Glaucoma is Alzheimer's disease of the eye.
