I think I'll just stay married.

Q. Why do husbands die before their wives?
A. Because they want to.

With the only variables being age and sex, it doesn't take anything into account. But it's still funny. 

It's not funny if you're a 105 year old male. It only gives you another year to go. And that graph goes almost Beachy Head-esque.

[Bealman]

Yeah, it sorta gives up after that. 

[Trainfish]

Try telling it you're 125 years old and either male or female. You'll be told you have a 1 in 4 chance of reaching infinity! And also a 1 in 10 chance of the same.

[Bealman]

Oh to live to infinity.

Sorta like standing between 2 mirrors.

Except no one has ever satisfactorily explained to me why your image curves off into the distance.
