The most interesting time of human life, I think, is when your heart
stops, and for between two and 15 minutes, your brain is still running.
I think the most interesting part of my life is going to happen in those
two to 15 minutes. Because time doesn't exist then. When the body's
gone and you've got 120 billion neurons whirring, it's like LSD. More
can happen in one minute than in a thousand lifetimes.
-- Timothy Leary, LSD guru who is dying of cancer
