So the serious investor can keep chasing the tau and amyloid theories, that's fine, and realize this is a failed theory as the big companies who are pulling their money out of the space have already figured out...I'll stick to investing based on the credibility of the science, which only has two realistic horses in the race AVXL and Neurotrope...I will bet on AVXL because it is easier to give, far better safety margin and has aligned its stars with success (follow the scientist, follow the money, follow the government involvement = AVXL)...I also will chose to believe the earth is round while the serious investor can keep chasing the earth is flat approach...then we will see who is right...good luck, maybe the world really is flat...
Go AVXL
