I must disagree. The half million who die of heart attacks every year are out of a population of 300,000,000, making the heart attack rate 0.2%. The car accident rate becomes 0.01% if treated such (most people drive cars or are driven in them).
The population of active GA pilots is diminutive, about a quarter million according to my Google-Fu. Thus the rate of pilots dying in airplane accidents is 0.4%, or twice as high as the most common thing Americans die of. Moreover, you are susceptible to heart attacks at all times, whereas you are only susceptible to dying in an airplane crash when flying. Thus the fatality rate for GA is frighteningly high.
All that said, people do dangerous things all the time. Part of freedom, which this nation is supposed to be all about.
