Study: Men become grumpy around 70

A recent study found that 80% of the 1,315 men surveyed found that life improved around 50, as opposed to the 20% who said life didn't get easier until retirement age.

But the good times apparently have an expiration date. The men found that their happiness began to diminish around age 70, which NPR dubs "the approximate moment when grumpiness kicks in for men." The study, published in March's Psychology and Aging, shed some light on why the men, who were between the ages of 53 and 85 during the 15-year study, found that life improved at first, then started to be a downer around 70, the Fox News reported.

"Older adults," referring to those around 50, "on average have fewer hassles" explains lead author Carolyn Aldwin.

Per a press release, appraisals of hassles improved during one's 60s, then downgraded in one's 70s Aldwin points out that later-in-life hassles include health issues, the death of family and friends.

But she adds that old men aren't doomed to gloom, as there are new sources of happiness: "You may lose a parent, but gain a grandchild."
