Anecdotal evidence suggests that having a pet reduces cardiovascular mortality. Does it? You can imagine that trying to conduct a scientific can be difficult. There are many factors to consider: pre-existing risks profile of the pet owner, physical activity before and after pet ownership, marital status of the owner. Do pet ownership benefit men or women more? Well, the evidence is rather conflicting though. It is still worthwhile examining the evidence because if the benefits are there, we should be recommending pet ownership to many of all of you.
