While I was doing my exercises this evening, I thought about listening to T. Boone Pickens at the Association for the Study of Peak Oil & Gas (ASPO) conference I attended in Houston last month.

Peak Oil refers to the point where the total amount of oil extracted in the world starts to decline, for geological reasons. At that point there are still lots of reserves left, but it has become increasingly difficult to retrieve it. Here’s an up-to-date and unbiased overview of where things stand right now.

Pickens said the world cannot produce more than 85 million barrels per day (which was reached in 2005) yet present world demand is 87 – 88 million barrels of oil per day. By 2030, 22 years from now, total oil supplies will decline to 50 million barrels per day. That’s 35 million barrels less than is produced now.

Supply and demand being what it is, we can expect higher prices. How high? No one really knows. That whole subject is difficult to wrap one’s brain around.

T. Boone Pickens also said he was a great believer in exercise. I liked him right off. He related that many years ago his company (Mesa Oil) was one of the first companies to require that its employees take an exercise break.

He told us that even now, at 79 years of age, he still walks 40 minutes at 4 mph several times per week. I considered interrupting his talk and asking him at what heart rate, but decided not to. Now I regret that I didn’t. He was obviously the kind of guy who would know the answer. And I was truly curious.

Back in the Feeling Good post of April 23rd, I related the results of the treadmill test I’d taken a few days earlier. The test consisted of four three-minute intervals. By the last three minutes, which were set at 4.4 mph, I had reached a heart rate of 172-174 and had stabilized. I stopped at 2 minutes and 40 seconds.

I use that three minutes at 4.4 mph as a goal. I did 2 minutes 30 seconds yesterday. But I am also doing short bursts at 6 and 7 mph.

Although T. Boone Pickens is 6’2” or so and maybe he is just walking fast, still, 40 minutes at 4 mph is pretty good for someone who is 79 years old. I have to step it up.
