I heard this many years ago. Supposedly, a "true" story. Many years ago they did a scientific research study involving rats. They placed a rat in a tub of deep water to see how long it would survive. I forget the exact details but it was something like 2-3 hours before the rat was completely exhausted and dipped beneath the surface ready to die. The research scientist reached in at the last possible moment and pulled the rat out to safety.
The next day they tried the same experiment. Well, this very same rat treaded water for something like 13 hours!! In the previous experiment it had only lasted a couple of hours before giving up. Somehow it knew/believed that IF it just keep trying...Kept going..kept holding onto HOPE...that the hand was going to come down from above again and save it!
So, put me squarely in the "hope" camp, my friends.
Besides, it's much easier on the heart!
