Probably on a Los Angeles freeway.

How many times I could have died before now, and in how many different ways. And yet I came close only once: a speeding sedan ran a red light, hit three other vehicles, and jack-knifed into my rear wheel split second after I’d stepped out of my parked car. A bystander described the scene to me later. “You were a millimetre away from losing your legs,” he said.

In the early 90s, in the Andes, caught in an atrocious storm above 20,000ft with three others. We were all in a very bad way. Some guys close to us perished; we were lucky.

I got stabbed in the neck with a light tube during a wrestling “death match” two years ago. It was scary. I thought I was dying: your life does flash before your eyes.

I am flattered and embarassed by all the recent attention to my "Last Lecture." I am told that, including abridged versions, over six million people have viewed the lecture online. The lecture really was for my kids, but if others are finding value in it, that is wonderful. But rest assured; I'm hardly unique. Send your kids to Carnegie Mellon and the other professors here will teach them valuable life lessons long after I'm gone.

This is obviously not how I wanted things to turn out, but my wife and I have no regrets; we did everything I could to maximize my odds. And we want to thank everyone who has so graciously helped us. The really weird part of all this is that I'm not depressed. I'm not in denial (I assure you, I am fully aware of what is going to happen), nor am I whistling in the dark, but after having felt crappy and sick for 11 months, to finally be fully healthy again is so exhilarating that it's a wonderful emotional buoy. So I am going to enjoy each day very fully, and play hard with my kids until I can't.

Shortly after my terminal diagnosis, I knew that one of my biggest priorities was to create memories for my children. Chloe and Logan are both so young that it's likely they'll have no direct memories of me. Dylan is the oldest, and at 5 (turns 6 in December), his memories are likely to be fuzzy. Hence the engineering question: What would make for the sharpest, most visceral memory, esp. for a kid who loves animals? Answer: go for a Dolphin Swim!

When Jeff Zaslow's column appeared in the Wall Street Journal (WSJ), about a dozen publishers emailed me, asked if I would be willing to write a book based on it. (I found this laughable, since at the time the palliative chemo was not yet working, and I thought I was down to about 6 weeks of good health). When the palliative chemo started working and we had some breathing room, I mentioned this to Jai, and she told me she wanted to do it. She was, in fact, quite emphatic. We had always talked about my "writing the manual" for her and the kids in my remaining time, and Jai felt that if it were a "real" project, I might take it much more seriously.
