Should We Start Wearing Green Wristbands If We're Accepting Hugs Again?

Some people are ready for things like handshakes and hugs again, and some aren't. So how do you tell? Well, here's one idea . . .

A lot of conferences have started using colored WRISTBANDS as a way for people to know who's okay with physical contact, and who isn't. Red means stay six feet away . . . yellow means touching elbows is okay . . . and green means you're okay with things like handshakes, high-fives, and hugs again.

It's not a new idea. A company called Social Bands started selling the wristbands last year. But "The Wall Street Journal "just did a big story on it this week. And they're becoming more popular at big social events, like weddings.
