My apologies. I did not mean to write working hours correlates to stress. I just wanted to view an extra parameter for reference.
I am working longer hours now (and making more money) but less stress. My old job was half as many hours but the stress was overwhelming because of unrealistic targets that cannot be met regardless of effort/dedication. Boss wanted the impossible (ie. double the portfolio in null time) and put the responsibility under my tree. Waking up at night with new ideas and writing it down before going back to bed was a nightmare.
