| IMHO, I'd say genetics first, stress second, lifestyle third. This said because there are plenty of people who are junk-food consuming couch potatoes whose BG is a lovely 78 all the time, and will be until they die.
100 years ago, a mom with three children didn't spend all her time in the mommy van, carting the kids to soccer, ballet, baseball, basketball, T-ball, art, chess, etc. classes. (Not saying these are bad. They have a place). Kids came home from school, did their chores, studied, had some family time and were in bed by 9 p.m.! Same with the adults.
