What function did the pandemic play?
Stadiums are filling up once more. Through the pandemic, as video games went ahead, groups took some artistic steps to make issues look considerably regular. Cardboard figures of fans had been positioned in a number of the seats and crowd noise was piped in — a sports activities model of a comedy present chuckle observe.
Now, although, the crowds are again, and the hazard has returned.
