I’d guess it means, once you’ve been injured, you can make the bleeding stop.
I do that myself. It’s usually my hands that take the injury, so I clean the wound site, and then relax for a bit with my arm elevated.
In a minute or so, Presto!, “turn off bleeding” has been implemented.
All y’all make it sound so simple!
I will not drink.
But if I do, I will not get drunk.
But if I do, I will not stagger.
But if I do, I will not fall.
But if I do, I will not fall face down on the keyboard to prevent blood from getting between and under the keys...
Like that?
Yah. Got it. ;o]
