Oliver Sacks: What hallucination reveals about our minds

http://www.ted.com Neurologist and author Oliver Sacks brings our attention to Charles Bonnett syndrome -- when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in heartwarming detail and walks us through the biology of this under-reported phenomenon.

@lightandbeautiful umm what is wrong with you?

Homosexual activists understand the power of words.

Please visit my channel to watch a one-minute video clip in which popular atheist author Richard Dawkins admits that homosexual activists "hijacked the word 'gay'".

The word "homosexual" is more appropriate and accurate because it, unlike the word "gay", actually describes the behavior/attraction/relationsh­ip being discussed.

The word "gay" helps homosexual activists push their agenda.
