[Happy age] 23 is the happiest with 69 year old life
8 March 2018
Hannes Schwandt, a Centre For Economic Performance scholar at the Centre for British Studies, published a study on the happiness index and studied 23,161 German respondents aged 17 to 85 years. They expect life satisfaction in the next 5 years to be scored after 5 years. The results show that people are most satisfied with their own life at the age of 23 and 69. The happiness index is like a roller coaster and U-shaped.
