Thanks for posting this, you're an inspiration and I thank you for all the work you've done. It's great to hear a story from someone who was there at the beginning. Don't worry about deciding not to leave your CPU on because the noise bothered you, I first heard about it at the start of 2010 and dismissed it entirely for three years!
Sorry to hear about the disease. You're right to be comfortable with your legacy, it's a great one.
