You said: If you crossed the street 20-60 times a day for 25 years your risk of dying from being hit by a car would go way up.

I am no statistician, so I don't know if the odds go up for each time you cross the street. Theoretically the risk is the same each time, I think. But then again, I am just a lawyer, and former high school foreign language teacher. My son is good at math, though...

True - the the risk is the same each time. However, if you choose to take that risk more often (cross the street more often than normal), your overall chances of being hit over time will increase.

The risk is the same each time but cumulative for repetition.

Same thing for smokers; one cigarette/day is nothing compared to 2-3 packs/day.

[Doctor Stochastic]

He means that the total risk goes up. The risk per street crossing is the same each time. (Except for rush hour.)

For smoking, the total risk goes up each fag consumed.
