I retired from a high stress job with weird hours while being on call....
I define "high stress" by one phone call. The Lieutenant Governor of the state had his secretary call my personal line, and then she put him on the phone, and he proceeded to yell at me because he couldn't do something he needed to do, which was state business, but wasn't anything I could personally do anything about, except say, "yes, sir, Verizon and AT&T are working on it".
... I lost about 20 pounds almost immediately, and since then my weight has stabilized around 35 pounds lighter than I was when I walked out the last time and turned in my ID badge 11 years ago.
