So I just read about a 50 year old Chinese guy who ran a marathon in 3.5 hours while chain smoking. Now, I'm a smoker (I vape now and am trying to cut down on that as well) and when I was still a teenager I ran several miles on a trail in Daniel Boone State Park while smoking along the way but I was 16-17 years old and thought the irony of doing it was the greatest thing in the world. How on Earth this dude is doing it at 50 though is a mystery to me. I think it just goes to show that when you have a population of a billion one of them is going to be able to do something super human and crazy that makes the rest of us mere mortals look bad.
