This is a great set of comparative data; thanks for posting it.
I also just want to chime in with a word about
relative risk. This is one of my
hot buttons pet peeves nonlinearities (as I like to say) -- so many folks make choices about things they're willing to do, or
not willing to do, with no understanding of the actual relative risk (or safety) of one activity vs. another. Drives me nuts, OK?!

Ca. (edit) two orders of magnitude more risky (in terms of risk of death per unit
time invested in the activity) to travel by car than by plane.
I apologize that I no longer have the original citation for this particular data set. I first saw a presentation along these lines when I was in grad school by Bruce Ames (the "Ames Test" guy), who was disheartened by the way that data from "his" test were misused/misrepresented. In his own way, he was trying to recast the context of Ames Test data, but he was largely "preaching to the choir". I've never found a copy of Ames' slide (mind you, I was in grad school a
long time ago now). This graphic is taken from a Boston Globe article, but that's all I remember at this point.
