I just found that with my first family. I stared a 'nighttime' family last night. They're in their 20's so no issue on the speed. The parents of my first are in mid to late 50's. I swear a snail could pass them right now, they're moving that slow.

Ironically, they have 4 children, 2 are in college. The younger two girls are 14 and 16. Isn't there a saying somewhere about kids keeping you young.
