blood

Evin Schultz lives in an apartment complex down in Minneapolis, and tweeted a picture of what looked like blood dripping from the ceiling of his unit.

When 50,000 people decide not to do something, it gets noticed. That's how many fewer people have given blood so far in June, leaving the American Red Cross blood supplies extremely low.

Today, you can make a difference and help the American Red Cross during a time of need. It's World Blood Donor Day across the U.S. Take an hour out of your day and donate.

The American Red Cross is looking for your help to keep summer blood levels from dipping dangerously low. And you can help with a drive on Monday.
