Final answer:
A one point increase in life satisfaction at age 22 is associated with almost double the higher salary at age 29.
Step-by-step explanation:
A one point increase in life satisfaction at age 22 is associated with almost double the higher salary at age 29. This suggests that an increase in life satisfaction at a younger age can have a significant impact on future income.
For example, if someone's salary at age 29 is $50,000 and their life satisfaction increased by one point at age 22, their salary would be around $100,000.
