The story was about the personal lifestyle and "How I Work" of a remote manager, handling 800? people, and he was saying that he does not need to go to the office to work to stay productive and have the business running.
He was explaining there how he used an adjustable height desk, along with a treadmill, and how he found a way to work while walking outside with the laptop. He was monitoring himself and saw a spike in the heart rate when he did not leave home for two weeks, which in turn made him go for a walk more often.
Thanks!
Edit: The post had a lot of points, as I only read HackerNews' top stories through RSS
