I know at least one person who died in 2009 due to stress caused by business problems. This happened after two years of intense pressure and suffering. Depression, not eating well, not sleeping enough and other factors converged. One morning a stroke followed by a series of heart attacks ended his life.

I have personally ended-up in the hospital with intense palpitations due to a combination of stress, lack of sleep and dehydration all as a result of business issues. There's nothing wrong with me or my heart, today I regularly swim 1500m and participate in Master's competitions and training. Over time I learned to deal with business stress in various ways (swimming is part of it).

So, yes, it isn't military service but don't make the mistake of thinking that stress-related disorders --and even death-- are monopolized by soldiers.

Also: There have been a number of high-profile suicides mentioned on HN over the last few years. Likely there have been countless lower-profile suicides never mentioned.
