That is one of those neat skilly ous pick up in certain duties in the military. Human beings are amazingly adaptable, and being well behind enemy lines and constantly hunted and shot at is a GREAT motivator to change your impressed sleeping patterns. One of the first things I learned was that our sleeping patterns are set by habit, not biological imperative. As the amountof sleep you get decreases, your sleep patterns change. Instead of sleeping for 4-5 hours before sinking into REM sleep, you begin dreaming faster.
Personally, there are times I have taken a 10 minute power nap and woke up remembering my dreams. There were guys in my unit who could sleep for 5 minutes and go through an entire sleeping cycle. It is not that uncommon. What truly matters is not how long you sleep, but how much time you spend in various stages of the sleep cycle. The majority of the time you spend sleeping is wasted. When you adaapt to less sleep, your body adapts so that instead of constantly switching between stages in the sleep cycle, you have on continous cycle instead of several spikes. The military has been studying this for years, and while you cannot possibly remove the sleep requirement for a soldier, you can significantly decrease the time spent through conditioning. This is one of the few truly useful skills I picked up in the military. It has allowed me to be far more productive than I would have been otherwise.
You could...but would you?
I owned a business specilaizing in prototyping, short run production, and contract R&D. Not only was teamwork vital within our organization, but across multiple companies, sometimes on different continents (and more than once requiring "teamwork" from actively deployed astronauts). It was not unusuall for us to ne running a half dozen multi million dollar projects at a time where hours counted in the rush to get items to market or get a patent before a clients competitor could. That is one reason I worked so many hours. It is alway sbusiness hours somewhere, and generally wherever that was, we had some link in our supply chain there, or a client there, or another firm doing some of our farm out there.
As far as your computer programmer buddy goes, unless he is one of those VERY rare individuals who writes their own software from start to finish (not including hobbyists, who almost always do), then I think you are seriously underestimating the amount of teamwork it takes to get thousanRAB of lines of code to interact seamlessly where virtually any one line has the potential of crashing the whole program. Billions of dollars have been spent developing software to facilitate teamwork and communications between computer programmers because teamwork and communication is VITAL to its sucess.
Sports teams are used as teamwork examples becuase it is visual, familiar to most people, and the simplest example out there. It does not take much explanation. As far as business related teamwork examples, it is pretty poor, since next to running a sucessful business the teamwork exhibited in sporting events is relatively mundane.
So basically besides the rather sad "teamwork" and "communication" examples, it boils down to it being "fun". Heres a thought. Next time, instead of turning on a football game, go right on past that channel and find something on one of the multitude of educational channels. There are 13 different discovery channels now (14 if you speak spanish, though I think the spanish one is a simulcast), 4 different history channels, a half dozen decent news channels, and several tech channels. On Dishnetwork or online, there are multiple places that you can watch collecge classes. Try one of those. You might learn somethign that will someday be useful. Watching the football game, you KNOW you won't, becuase frankly if you have not learned all the really useful lessons that a football game has to teach you by the time you are 15, you should probably be beat over the head with a tack hammer because there is obviously something wrong with you. 2 points to anybody who can identify the literary allusion there...don't remember the name of the movie but it had that fat guy who died of the cocaine overdose in it.
As far as whether or not I know what "fun" is, if I didn't, I would not have worked as hard as I did. I now have the majority of my life to do whatever I want with it, and have acquired enough to ensure that funRAB are not a problem. I can spend 24 hours a day, 7 days a week with my family if I wanted (though I would not recommend that...insanity is sure to ensue). If I felt so compelled, I could fly around the country and go to every football game played (though I cannot imagine a bigger waste fo time and money). What is surprrising is how easy it was to pull off. We live in a country, and maybe a world, where medicority is the norm and people waste massive amounts of time in pursuit of leisure using rediculous, half assed explanations like "a person is not a robot, you need time to relax...blah blah blah". Pushing yourself just a little beyond mediocrity, trying to learn just a little more than the average joe, pushing just a little harder than the next guy can pay off hanRABomly.
If you are happy being a rank and filer for the rest of you rlife, by all means sit around drooling in front of a football game and telling yourself "this is really quite educational". I am sure you can retire at 60 or 65, at which point you have a good 10, or maybe even 20 years of life left. There is a good chance that nearly half of those will be active years where you have the time and energy to enjoy yourself. Otherwise, you might look for wiser ways to spend your recreational time. I cannot even count the number of times that some obscure fact set I picked up in a book or on an educational television program has proven itself useful, and could not even estimate the number of times that working just a little harder than the next guy or setting the bar just a littel higher has paid off.
