Here is a fun one.
Richie opens and drinks two coconuts in 36 seconds
I had to laugh at that. TIGHAR members might remember me doing an experiment opening a couple of green coconuts on a deserted island using only a rock. Took a lot longer than 18 seconds each ROFL.
But it was possible and the watch shows that is was not a ridiculous time. I still have the photos somewhere, but I think it was about 10 minutes a nut.
Now, I had never opened a nut without some sort of tool before, and I assume Fred and Amelia might have been in the same situation. I stayed at this island for a week or so and while I was there I drank only coconut water for most of the stay, from nuts I gathered. Not easy in a place where nuts are not native. But it proved a point. No dysentery, despite all the horror stories predicting tummy upsets, and no excessive thirst in 34 degrees C.
