Lol, i would argue that engineers, many of whose primary job function is to imagine worst case scenarios and engineer around those to prevent accidents, data loss, etc. Are the exact type of people that are prone to hypochondria. It's not about growing old and dying, it's about ignoring a stomach ache for a couple months and then being told you have terminal cancer, and then living with the regret of "if only I got it checked out earlier".
In the engineering world, you are almost always rewarded for being extra safe and testing, fixing, and investigating anything that might seem a little off. If you do blood tests, MRIs, and cancer screens for every mole, cough, and stomach pain, you will go insane and develop hypochondria.
