How much of a difference will there be in your 60s between someone who managed their health from their 30s and someone who didn't?

A: Does zero exercise, eats delivery food, loves highly seasoned/stimulating food, and is a case of skinny fat
B: Doesn't drink at all, does cardio and weights 4–5 times a week, and eats a balanced diet with proper nutrients
When they get older, what would be the difference in value if we were to calculate it in terms of money?
