Reasoning for above- fibbonacci would leave us with 30 (too young), 60 ( BINGO!!!!!!!!!!!! ), 90 (too old), 120 (WAYY TOO OLD!!) and so on with multiples of 30. However, you said fords were not around when you were born. If we all remember, Ford turns 100 this year. That means that the next age older than 90 that is pre-ford is 120, and that is too old, that is a false statement.

(Yes, I know I am a smarty-pants. )

So, now I let the cat out of the bag-60!!!

Happy Birthday John!!!

Let's go for 60 more!!!!!!
