I want to know the answer to the following question:
What year did a publication come out indicating having a pet does not mean lower risk of heart disease in the elderly?
All the background I'm provided with is that "In one study, new guardians reported a highly significant reduction in minor health problems during the first month following pet acquisition, and this effect was sustained in those with dogs through to the end of the study.". Is that enough to answer the question?
Answer: no
