How long can you tread water?
I see what you did there.
That reminds me of a fun bible study I attended. The guy used a medical study on drowning rats to make his point.
A group of rats were drowned, all but one. They lasted about 6 minutes. Then the 2nd group was drowned, alongside a control group. The control group lasted about 6 minutes but the other group had that one rat who had survived. He swam around and encouraged the others. They lasted 15 minutes.
The guy said that this rat had communicated HOPE to these other rats. “In this case, false hope”. Everyone cracked up.
