Everyone who got to 100 made it to 90.Don't go to a Casino FactFinder, is all I can say ..
And now I'll say something ..
Excluding the green zero on a roulette table for example, the odds of red or black coming up, are always 50%.
It does not matter if red has come up 22 times in a row (which I've heard of, personally I've seen 11..) the odds of black coming up next, are still only 50%.
I don't think the 90 year old, has any more chance of reaching 100, than the 20 year old.
Without considering all the factors of the state of their health at 90, there is also the advancement over the next just 20 years, that could extend the lifespan of the younger individual.
There are just too many variables..
There's the chance the 20 year old could die of alcohol poisoning on his 21st birthday..
But if I had to lay a bet, it would be on the 20 year old, reaching 100, before the 90 year old.
Centennials, are still relatively rare.
Out of the 7.8 billion people in the world, there are only about 316,600 — or 0.004% — centenarians living today
But I'm sorry, I'm not trying to be argumentative ..
And I haven't bet at the Casino in years..
Not everyone who made it to 20 made it to 100.
