From the headline I expected this article to be about over working and exhaustion, a topic I'm sure many here can relate to in some way. In the authorised biography of Steve Jobs, he comments on how he believes the exhaustive hours worked in 1997 when driving back and forth between Apple and Pixar were the cause for his cancer. In a similar vein, there seems to be a higher ratio of cancer sufferers in high pressured environments like financial trading. As a developer wanting to achieve amazing things, working what others consider crazy hours, the worry does occasionally cross my mind. I love what I do, but I do wonder how much harm can be caused by over working, regardless of the fact that there's nothing else I'd rather do with my time.
