I agree wired...women burning-out while men deal with constant high cortisol is a trend for sure.
Maybe it has to do with perhaps men have stronger adrenals in order to handle stress..being the 'hunter' gender...so it takes a lot more stress to burn-out a man.
Probably why women traditionally have not been given high powered jobs due to the excess stress levels...Thatcher being a good example!
Sounds gender-ist i know but there might be something to it!
