Yes, agreed. I think in this industry we ought to sometimes reflect on how hard we expect everyone to work, and how hard we push people who may not always be in situations where they should be pushing.
I'm generally a believer that hard work is good and that startups are worth investing considerable time and energy into, and I love my career. But working in this industry has certainly been hard on my health, despite ALL my other choices being very "healthy." Leaders have pushed me to ignore my body in order to produce results many times, over prolonged periods of time.
If you don't mind, I won't get into the specific type of cancer here, I'm particularly protective of my ability to remain psychologically positive about it and I don't want to encounter HN-style analysis of my specific type.
