In the wake of disasters like Hurricane Harvey, you often hear calls to donate blood. In this instance, it was people who gave blood before the storm who helped the disaster victims.

If you give blood at this point, your donation is likely to stay home -- where it is welcome and needed.

If you give blood, usually it goes into a plastic bag in a fridge until someone needs it. But when you’re deep in the countryside or tundra or out at sea, there’s no hospital—and no blood bank.

The Oregon House is set to vote Monday on a measure that would require a doctor or nurse to be on hand when you donate a pint of blood.
