In Reference to: Thomas A. Edison
1 - The quote, whatever it was, may have made sense. That doesn't mean Edison practiced what he preached during much of his life.
2 - All I've found so far is that he supported (and/or practiced?) vegetarianism at some point because he had health problems. Supposedly, he also said he was a vegetarian to make better use of his brain or something to that effect.
3 - I'm not going to start using a kerosene lamp or going to bed at sundown. I also don't like the idea of electrocution.
