Let me propose the following scenerio that might help you reach a decision.
Imagine that you have a very very precious 6 year old daughter at home.
Imagine that you had to give your daughter a drug and you had a choice of two
forms of the drug. One form was cheaper for the drug company to make and thus
the company made more profit and those holding its stock are able to retire at
55 rather than 65. On the other hand your daughter has a 0.001% chance of
being exposed to a bovine prion that might rot her brain. Your other choice is
the same drug but with 0% chance of your daughter having a rotted brain. Which
drug would you choose?
