Not exactly. The odds ratio applies to any point in time; it's
neither cumulative or additive. I have a 98.75% chance of being here

If you have a 98.75% chance of being here tomorrow, then you have a
98.75% x 98.75% chance of being here a day after that, a 98.75% x
98.75% x 98.75% chance of seeing Sunday and so on.

Sure, /if/ you make it to 1st November 2008 you have a 98.75% chance
of making it to 2nd ... but there's only a 1% chance, on these
figures, that you'll put it to the test.
