Our happiness in life goes in waves throughout the years, peaking when we're age 23, dipping down in the mid-50s, and peaking again when we're 69, according to a new study.
"People in their 50s could learn a little from the elderly, who generally feel less regret. They should try not to be frustrated with their unmet expectations because they are probably not feeling much worse than their peers," study researcher Dr. Hannes Schwandt, of Princeton University, said in a statement.
