I'll try to be more specific. People die because various falling things break their heads (e.g. icicles at winter or bunch of keys accidentally dropped from the 10th floor etc). Do you wear a helmet to protect yourself? You may also be stung by a bee/wasp or bitten by a snake/spider/mad dog etc. Do you have an anti-allergen and ant-dote in your pocket? Etc...
Thus if you don't even consider those other threats, but you always carry a gun, I can suggest that this particular sort of a threat seriously overweights all others in your living/working area.
Just a simple logic.
