Since you're giving 7 yes/no answers, the app can pick different combinations of the numbers to identify up to 2^7 = 128 different possible choices. That's more than enough to guess your age. Basically, the numbers are presented in an order so that only one age will come out at the end. It looks at the digits of your age in binary, one at a time. So the first question will ask about 1, 3, 5... all numbers with a 1 in the last binary digit. The next will ask about 2,3,6,7, .... all numbers with a 1 in the next to last binary digit. Etc., until it knows the whole number.

How old do you have to be to get on a plane?
There is no age limit, but I think you have to be 18 or older to go on a plane by yourself, or whatever age your country considers an adult, I guess.

How old would a person born in 1961 be?
There's an app for that! Launch your "calculator" app and type in the current year -- you can go to your "calendar" app to find it is currently 2010 -- and then press the "-" key, also called "minus" or "take-away" key and then type in 1961 and press the "=" key, also called the equals key. The number displayed should be 49 meaning the person would be 49 years old. Yay! I guess schools don't teach math anymore.
