I had a CS professor die mid term.  He was 50.  <a href="http:&#x2F;&#x2F;wiki.yak.net&#x2F;77" rel="nofollow">http:&#x2F;&#x2F;wiki.yak.net&#x2F;77</a>   He was out for a jog.<p>Dennis Ritchie died at age 70.  Heart problems &amp; prostate.<p>Steve Jobs. Age 56. Pancreatic cancer.<p>Of course these are just a few.  CS is a young field, but by now we should have enough statistics to begin to reveal how a (very) sedentary lifestyle affects lifespan.
