A while back .. 15 -20 years ? .. 'Pilot' magazine investigated this topic and the conclusion IIRC was that private flying is statistically about as dangerous as motorcycle racing. Dunno whether this reassures or not. Probably not.
Another way of looking at it was that it about doubles the chance of dying from all causes if you are aged 50+. Again IIRC. Put another way, at 50+ your chance of popping your clogs from all causes is beginning to climb. So if you are 50+ (like me) the additional risk of flying is merely a relatively smaller and smaller additional risk to add to all the others as time passes !
However, if you are below the age of 25 and, by definition, probably still regard yourself as immortal, you are assuming a much bigger (relative) risk than me !
Caveat aviator.
