Why adults love Halloween, too

• 62% know some neighbors. But another 12% say they don't know a single one.

The big picture: Knowing your neighbors is better for your mental health, longevity and happiness levels, studies have shown.

• And the casual relationships we have with people nearby — the folks we wave to or chat with at the mailbox — are what keep communities strong and connected.

Reality check: A little more neighborliness can't solve everything straining American society right now.

• But it certainly couldn't hurt to at least be on a first-name basis with a few folks on your block or in your building.
• You never know when you might need some help shoveling your sidewalk or jumping your car, and communities can rally together in times of need.

Yes, but: You don't have to wait for Halloween to meet your neighbors.

• Spend some time out in your front yard, say hi to folks doing yard work or washing their car as you walk around, or go to your community yard sales and other events.

The bottom line: Making a few neighborhood friends is sweeter than any Snickers.
