Women are expected out outlive men by about two or three years. Why is that? While there may not be one single answer to that question, one of the many may have to do with the fact that men visit the doctor far less than women.

According to WebMD, a survey of 1,100 men revealed that 85 percent of men saw a doctor if they felt ill, but typically waited for a few days to first see if their ailment dissipated on its own. It's important to note that most of the men in the survey had medical insurance and were registered patients of a primary care physician.

When asked why they were reluctant to visit the doctor, most men responded that they only did so when they were extremely sick. Others stated that they did not have the time, while some asserted that they were averse to taking medicine.

A remarkably high 80 percent of the survey repentants rated their health as either good or excellent, though the results of the survey suggested otherwise. Perhaps one of the reasons for this disparity, aside from the disinclination to visit a doctor when feeling ill, is that men spent an average of 18 hours per week watching television but only 5 hours per week exercising.
