William James reported that a friend of his who was experimenting with nitrous oxide gas kept thinking he'd solved the riddle of the universe when high, but kept forgetting what he'd figured out when he woke up in the morning, so he kept a pen and paper next to him while high and rushed down the following morning to see that he'd written "A smell of petroleum prevails throughout."

Love your pearl of wisdom. Don't know if this was the intent, but it made me laugh despite feeling a bit sad today.

At least you now have a title for your autobiography!
