This study on longevity over eight decades seems to debunk a few beliefs that I've been taught. Study says: Cheery people die sooner [really good news for you Politically Incorrect regulars!] Having pets doesn't necessarily = a longer life. Less surprising is that substituting human/human social contact with pet interaction = shorter life. Also not surprising [to me at least] that retiring early can shorten one's life too. Statistical population was Californians ... not sure how or if the findings correspond to normal people.
