Intergenerational bonds come with a slew of perks — but they're not that common.

🧮 By the numbers: Some 37% of Americans say they have a friend who is at least 15 years younger or older than they are, according to AARP.

• But intergenerational friendships are more common among older generations — Gen X (41%) and boomers (39%) — than millennials (32%).

Why it matters: Those who have older friends say those pals inspire them, give them a new perspective and act as role models.

• Older folks with younger buds say those friends boost their energy, make them feel valued and keep them up on trends.

🔎 Zoom in: People are likely to meet their friends from other generations at work (26%) or at church or temple (11%), AARP notes.

• People say these friendships are also likely to stand the test of time. Nearly half of those responding to an AARP survey said their intergenerational friendships have lasted over 10 years.

The bottom line: Whether you're fresh out of college or well into retirement, striking up a bond with someone a generation or two removed can bring you joy.

"My song of the summer is ''Til Summer Comes Around,' by Keith Urban," Finish Liner Glenn W. of Norman, Okla., tells us.

• "It reminds me of my days at sleep-away camp when I only saw some people for 8 weeks a year. I was sad that camp was ending, but I always looked forward to seeing my camp friends the next summer."
