Shift work and global jet-setting discouraged for mice

Talk about something cruel and fruitless. Like there aren't enough human shift workers or people in the travel industry for epidemiological research on this? Dont' we suppose that risk and protective factors, and covarying lifestyle factors might be salient (i.e. shift workers' SES versus jetsetters' SES?)? Mice tend to under-report such things.
