I looked surprised but wasn’t; this was a "simulated question" for which an answer had been taped. "Nobody knows how long a person will live in Luna; we haven’t been there long enough. Our oldest citizens were born Earthside, it’s no test. So far, no one born in Luna died of old age, but that’s still no test; they haven’t had time to grow old yet, less than a century. But—Well, take me, madam; how old would you say I am? I’m authentic Loonie, third generation."
