When I had my first Medicare physical my doctor asked me that question.  I asked him why he asked.  He said that as we age the incidence of bouts of depression increases and that having a gun in the house increases the risk of suicide when one of those bouts occurs.  My doctor's name:  Kenneth Atkinson.  Maybe you remember him.  Killed by his gun-weilding neighbor who was experiencing a bout of depression.  So I'd trade your right to have a gun for my right to have my doctor back in a heartbeat.
