A new study finds that in mid-life, most people are likely to experience the blues.
Researchers looked at data from 2 million people in 80 countries and found the low point in life falls in your forties.
Researchers found people across the globe are the happiest in their 20s and 30s and then again in their 50s, 60s and 70s.
"The 40s are the lowest point all over the world," said Andrew Oswald, an economist at Warwick University.
Gail Harris agrees. She describes her mid 40s as a time of heartache. She went through a divorce and changed careers.
"You start assessing where you are and wondering is that all there is? Could you be happier?" she said. "Something almost magical and mysterious happens as you round the bend to 50."
Her bright smile says it all -- at 56 years old, Gail says she's the happiest she's ever been.
Researchers crunched the numbers and found that among the millions of people they studied, the age of 44 was the lowest point.
"The most plausible theory is that at the start of life, we have very high expectations, high aspirations, and it's painful in your 30's and then in the 40s to let them go," Oswald said.
According to the study, once people get beyond their 40s, they become happier -- much happier.
"People cut themselves a little slack," Oswald said.
Susan Bluestone, a therapist in New York, agrees that people are beginning to give themselves a break.
"It's not settling. It's different. It's really understanding who you are, and what you really can accomplish in life," she said.
Harold Goldman is now in his 70s. He recalls his 40s.
"I think you say to yourself, is this how you always want to be?" he said.
Gail Harris took a closer look at her life, and now through a new Web venture, she wants to help others facing the mid-life blues.
