Last night my wife selects this "award winning" Robert Redford movie because she is obsessed with sharks. I like to learn new survival skills but am doubtful about any Hollywood version of it. Surprisingly my 16 year old daughter manages to endure the first 30 minutes mostly on her phone using "SM" and T.M." apps, but my outcries of "What!? the Noob's SAT phone was not in a dry box! I keep that thing double or triple protected especially in a marine environment!" finally drove her out of the room.
So one of the few wise things the only character in this movie does is to use a hammock to sleep in. And like a few of us he does not get sea sick easily swinging back and forth so it appears to work for him. For those of you who have not seen this movie, I recommend NOT watching the trailer, but DO have a legal pad of paper and pen and write down all the foolish things he does and wise choices as well, then calculate the ratio. See if you get close to a 10:1.
The Discovery Channel's one hour show about Steven Callahan who survived 76 days at sea on a raft was much better and actually educational, but he did not to use a hammock or it was not shown. Also my wife and kids only watch shark week on Disc Ch. everything else is "nerdy".
