If you worry about getting sick, are you more likely to become ill? This doesn’t sound fair but alas, it may be true.
It works that way with rats, anyway. Robert Roy Britt writes in LiveScience.com that when young female rats, of a breed that is know to be cancer-prone, were placed in an unfamiliar environment, the ones that became apprehensive developed cancerous tumors much sooner than the rats with more equanimity. There was no difference between the time they got the cancer and the time of death in the two sets of rats?the apprehensive ones just got sick sooner.
There’s a lesson there for humans in how to live.
