An Aldous Huxley quote. Not the one I went looking for, just one that distracted me.
The one I was looking for was:
"It is a bit embarrassing to have been concerned with the human problem all one's life and find at the end that one has no more to offer by way of advice than 'Try to be a little kinder.'"Those were not his last words. His last words were instructions for injecting him with LSD. An eternal life strategy?
ADDED: LSD, it's good for dying. It's the blue pill, that works better for you, grandfather:
