' A FISTFUL OFWhat does it mean to talk about

the risk of, say, being in an airplane

crash or being snuck by lightning?

Calculations of risks are averages,

so they have limited value to the

individual. Airplanes, for Instance,

may be safe in terms of death:

passenger mile, but that says 1

about the flight you’re abet

board-one that entails sev

takeoffs and landings in bad weather, on a day following a night

when the pilot may have had a few too many. To state a risk im-

plies a foretelling, but this predictive power is misleading. Risk

calculations almost always use historical data and mask the du-

Riskiest meals out (inMinnesota):Minnesota may not be repre-sentative of the country as awhole, but no other statekeeps such close tabs on whogets sick where. We arrived at

these figures by estimatingthat each state resident goesto each type of restaurantonce a year-which may notbe the case. At any rate, here’syour yearly risk of being poi-soned at the following:IT.%L4N RESTAL’R~\-F

Here are some risky activitiesand the associated costs to lifeexpectancy. The figures give afeeling for relative risks, butit would be silly to take themliterally.DRIVING WITHOUT A SEATBELT ON
