Something weird, something wonderful...

I want to roll up a community, an asteroid settlement. Random age and gender, age is least out of two % rolls, so 78, 18 is an 18 year old teenager... And a girl because 18 is less than 78? 18, 78 would be an 18 year old boy.

46, 93 is a 46 year old man; default question is the character a female, a woman or a girl, and the lesser number is age. The age distribution scues to lower numbers. I need to run a Monte Carlo simulation, but about half are under thirty.
