Why the chubs?

My last post dealt with the thorny issue of obesity, both it’s increasing presence in our everyday lives, and what for me is the underlying reason behind the stats that back up media scare stories concerning ‘the obesity epidemic’- the rise in size of the ‘average’ person over the last few decades. The precise causes of this trend can be put down to a whole host of societal factors within our modern age, but that story is boring as hell and has been repeated countless times by commenters far more adept in this field than me. Instead, today I wish present the case for modern-day obesity as a problem concerning the fundamental biology of a human being.

We, and our dim and distant ancestors of the scaly/furry variety, have spent the last few million years living wild; hunting, fighting and generally acting much like any other evolutionary pathway. Thus, we can learn a lot about our own inbuilt biology and instincts by studying the behaviour of animals currently alive today, and when we do so, several interesting animal eating habits become apparent. As anyone who has tried it as a child can attest (and I speak from personal experience), grass is not good stuff to eat. It’s tough, it takes a lot of chewing and processing (many herbivores have multiple stomachs to make sure they squeeze the maximum nutritional value out of their food), and there really isn’t much of it to power a fully-functional being. As such, grazers on grass and other such tough plant matter (such as leaves) will spend most of their lives doing nothing but guzzle the stuff, trying to get as much as possible through their system. Other animals will favour food with a higher nutritional content, such as fruits, tubers or, in many cases, meat, but these frequently present issues. Fruits are highly seasonal and rarely available in a large enough volume to support a large population, as well as being quite hard to get a lot of down; plants try to ‘design’ fruits so that each visitor takes only a few at a time, so as best to spread their seeds far and wide, and as such there are few animals that can sustain themselves on such a diet.  Other food such as tubers or nuts are hard to get at, needing to be dug up or broken in highly energy-consuming activities, whilst meat has the annoying habit of running away or fighting back whenever you try to get at it. As anyone who watches nature documentaries will attest, most large predators will only eat once every few days (admittedly rather heavily).

The unifying factor of all of this is that food is, in the wild, highly energy- and time-consuming to get hold of and consume, since every source of it guards its prize jealously. Therefore, any animal that wants to survive in this tough world must be near-constantly in pursuit of food simply to fulfil all of its life functions, and this is characterised by being perpetually hungry. Hunger is a body’s way of telling us that we should get more food, and in the wild this constant desire for more is kept in check by the difficulty that getting hold of it entails. Similarly, animal bodies try to assuage this desire by being lazy; if something isn’t necessary, then there’s no point wasting valuable energy going after it (since this will mean spending more time going after food to replace lost energy.)

However, in recent history (and a spectacularly short period of time from evolution’s point of view), one particular species called homo sapiens came up with this great idea called civilisation, which basically entailed the pooling and sharing of skill and resources in order to best benefit everyone as a whole. As an evolutionary success story, this is right up there with developing multicellular body structures in terms of being awesome, and it has enabled us humans to live far more comfortable lives than our ancestors did, with correspondingly far greater access to food. This has proved particularly true over the last two centuries, as technological advances in a more democratic society have improved the everyman’s access to food and comfortable living to a truly astounding degree. Unfortunately (from the point of view of our waistline) the instincts of our bodies haven’t quite caught up to the idea that when we want/need food, we can just get food, without all that inconvenient running around after it to get in the way. Not only that, but a lack of pack hierarchy combined with this increased availability means that we can stock up on food until we have eaten our absolute fill if so we wish; the difference between ‘satiated’ and ‘stuffed’ can work out as well over 1000 calories per meal, and over a long period of time it only takes a little more than we should be having every day to start packing on the pounds. Combine that with our natural predilection to laziness meaning that we don’t naturally think of going out for some exercise as fun purely for its own sake, and the fact that we no longer burn calories chasing our food, or in the muscles we build up from said chasing, and we find ourselves consuming a lot more calories than we really should be.

Not only that, but during this time we have also got into the habit of spending a lot of time worrying over the taste and texture of our food. This means that, unlike our ancestors who were just fine with simply jumping on a squirrel and devouring the thing, we have to go through the whole rigmarole of getting stuff out of the fridge, spending two hours slaving away in a kitchen and attempting to cook something vaguely resembling tasty. This wait is not something out bodies enjoy very much, meaning we often turn to ‘quick fixes’ when in need of food; stuff like bread, pasta or ready meals. Whilst we all know how much crap goes into ready meals (which should, as a rule, never be bought by anyone who cares even in the slightest about their health; salt content of those things is insane) and other such ‘quick fixes’, fewer people are aware of the impact a high intake of whole grains can have on our bodies. Stuff like bread and rice only started being eaten by humans a few thousand years ago, as we discovered the benefits of farming and cooking, and whilst they are undoubtedly a good food source (and are very, very difficult to cut from one’s diet whilst still remaining healthy) our bodies have simply not had enough time, evolutionarily speaking, to get used to them. This means they have a tendency to not make us feel as full as their calorie content should suggest, thus meaning that we eat more than our body in fact needs (if you want to feel full whilst not taking in so many calories, protein is the way to go; meat, fish and dairy are great for this).

This is all rather academic, but what does it mean for you if you want to lose a bit of weight? I am no expert on this, but then again neither are most of the people acting as self-proclaimed nutritionists in the general media, and anyway, I don’t have any better ideas for posts. So, look at my next post for my, admittedly basic, advice for anyone trying to make themselves that little bit healthier, especially if you’re trying to work of a few of the pounds built up over this festive season.

*”It is sweet and right to die for your country”

Patriotism is one of humankind’s odder traits, at least on the face of it. For many hundreds of years, dying in a war hundreds of miles away from home defending/stealing for what were, essentially, the business interests and egos of rich men too powerful to even acknowledge your existence was considered the absolute pinnacle of honour, the ultimate way to bridge the gap between this world and the next. This near-universal image of the valiance of dying for your country was heavily damaged by the first world war, near-crushing “the old lie: Dulce Et Decorum Est/Pro Patria Mori*” (to quote Wilfred Owen), but even nowadays soldiers fighting in a dubiously moral war that has killed far more people than the events it was ‘payback’ for are regarded as heroes, their deaths always granted both respect and news coverage (and rightly so). Both the existence and extent of patriotism become increasingly bizarre and prevalent when we look away from the field of conflict; national identity is one of the most hotly argued and defended topics we have, stereotypes and national slurs form the basis for a vast range of insults, and the level of passion and pride in ‘our’ people and teams on the sporting stage is quite staggering to behold (as the recent London 2012 games showed to a truly spectacular degree).

But… why? What’s the point? Why is ‘our’ country any better than everyone else’s, to us at least, just by virtue of us having been born there by chance? Why do we feel such a connection to a certain group of sportspeople, many of whom we might hate as people more than any of their competitors, simply because we share an accent? Why are we patriotic?

The source of the whole business may have its roots in my old friend, the hypothetical neolithic tribe. In such a situation, one so small that everybody knows and constantly interacts with everyone else, then pride in connection with the achievements of one’s tribe is understandable. Every achievement made by your tribe is of direct benefit to you, and is therefore worthy of celebration. Over an extended period of time, during which your tribe may enjoy a run of success, you start to develop a sense of pride that you are achieving so much, and that you are doing better than surrounding others.

This may, at least to a degree, have something to do with why we enjoy successes that are, on the scale of countries, wholly unconnected to us, but nonetheless are done in the name of our extended ‘tribe’. But what it doesn’t explain so well is the whole ‘through thick and thin mentality’- that of supporting your country’s endeavours throughout its failings as well as its successes, of continuing to salvage a vestige of pride even if your country’s name has been dragged through the mud.

We may find a clue to this by, once again, turning our attention to the sporting field, this time on the level of clubs (who, again, receive a level of support and devotion wholly out of proportion to their achievements, and who are a story in their own right). Fans are, obviously, always proud and passionate when their side is doing well- but just as important to be considered a ‘true’ fan is the ability to carry on supporting during the days when you’re bouncing along the bottom of the table praying to avoid relegation. Those who do not, either abandoning their side or switching allegiance to another, are considered akin to traitors, and when the good times return may be ostracized (or at least disrespected) for not having faith. We can apply this same idea to being proud of our country despite its poor behaviour and its failings- for how can we claim to be proud of our great achievements if we do not at least remain loyal to our country throughout its darkest moments?

But to me, the core of the whole business is simply a question of self-respect. Like it or not, our nationality is a huge part of our personal identity, a core segment of our identification and being that cannot be ignored by us, for it certainly will not be by others. We are, to a surprisingly large degree, identified by our country, and if we are to have a degree of pride in ourselves, a sense of our own worth and place, then we must take pride in all facets of our identity- not only that, but a massed front of people prepared to be proud of their nationality in and of itself gives us a reason, or at least part of one, to be proud of. It may be irrational, illogical and largely irrelevant, but taking pride in every pointless achievement made in the name of our nation is a natural part of identifying with and being proud of ourselves, and who we are.

My apologies for the slightly shorter than normal post today, I’ve been feeling a little run down today. I’ll try and make it up next time…

A Brief History of Copyright

Yeah, sorry to be returning to this topic yet again, I am perfectly aware that I am probably going to be repeating an awful lot of stuff that either a) I’ve said already or b) you already know. Nonetheless, having spent a frustrating amount of time in recent weeks getting very annoyed at clever people saying stupid things, I feel the need to inform the world if only to satisfy my own simmering anger at something really not worth getting angry about. So:

Over the past year or so, the rise of a whole host of FLLAs (Four Letter Legal Acronyms) from SOPA to ACTA has, as I have previously documented, sent the internet and the world at large in to paroxysms of mayhem at the very idea that Google might break and/or they would have to pay to watch the latest Marvel film. Naturally, they also provoked a lot of debate, ranging in intelligence from intellectual to average denizen of the web, on the subject of copyright and copyright law. I personally think that the best way to understand anything is to try and understand exactly why and how stuff came to exist in the first place, so today I present a historical analysis of copyright law and how it came into being.

Let us travel back in time, back to our stereotypical club-wielding tribe of stone age human. Back then, the leader not only controlled and lead the tribe, but ensured that every facet of it worked to increase his and everyone else’s chance of survival, and chance of ensuring that the next meal would be coming along. In short, what was good for the tribe was good for the people in it. If anyone came up with a new idea or technological innovation, such as a shield for example, this design would also be appropriated and used for the good of the tribe. You worked for the tribe, and in return the tribe gave you protection, help gathering food and such and, through your collective efforts, you stayed alive. Everybody wins.

However, over time the tribes began to get bigger. One tribe would conquer their neighbours, gaining more power and thus enabling them to take on bigger, larger, more powerful tribes and absorb them too. Gradually, territories, nations and empires form, and what was once a small group in which everyone knew everyone else became a far larger organisation. The problem as things get bigger is that what’s good for a country starts to not necessarily become as good for the individual. As a tribe gets larger, the individual becomes more independent of the motions of his leader, to the point at which the knowledge that you have helped the security of your tribe does not bear a direct connection to the availability of your next meal- especially if the tribe adopts a capitalist model of ‘get yer own food’ (as opposed to a more communist one of ‘hunters pool your resources and share between everyone’ as is common in a very small-scale situation when it is easy to organise). In this scenario, sharing an innovation for ‘the good of the tribe’ has far less of a tangible benefit for the individual.

Historically, this rarely proved to be much of a problem- the only people with the time and resources to invest in discovering or producing something new were the church, who generally shared between themselves knowledge that would have been useless to the illiterate majority anyway, and those working for the monarchy or nobility, who were the bosses anyway. However, with the invention of the printing press around the start of the 16th century, this all changed. Public literacy was on the up and the press now meant that anyone (well, anyone rich enough to afford the printers’ fees)  could publish books and information on a grand scale. Whilst previously the copying of a book required many man-hours of labour from a skilled scribe, who were rare, expensive and carefully controlled, now the process was quick, easy and available. The impact of the printing press was made all the greater by the social change of the few hundred years between the Renaissance and today, as the establishment of a less feudal and more merit-based social system, with proper professions springing up as opposed to general peasantry, meaning that more people had the money to afford such publishing, preventing the use of the press being restricted solely to the nobility.

What all this meant was that more and more normal (at least, relatively normal) people could begin contributing ideas to society- but they weren’t about to give them up to their ruler ‘for the good of the tribe’. They wanted payment, compensation for their work, a financial acknowledgement of the hours they’d put in to try and make the world a better place and an encouragement for others to follow in their footsteps. So they sold their work, as was their due. However, selling a book, which basically only contains information, is not like selling something physical, like food. All the value is contained in the words, not the paper, meaning that somebody else with access to a printing press could also make money from the work you put in by running of copies of your book on their machine, meaning they were profiting from your work. This can significantly cut or even (if the other salesman is rich and can afford to undercut your prices) nullify any profits you stand to make from the publication of your work, discouraging you from putting the work in in the first place.

Now, even the most draconian of governments can recognise that your citizens producing material that could not only benefit your nation’s happiness but also potentially have great material use is a valuable potential resource, and that they should be doing what they can to promote the production of that material, if only to save having to put in the large investment of time and resources themselves. So, it makes sense to encourage the production of this material, by ensuring that people have a financial incentive to do it. This must involve protecting them from touts attempting to copy their work, and hence we arrive at the principle of copyright: that a person responsible for the creation of a work of art, literature, film or music, or who is responsible for some form of technological innovation, should have legal control over the release & sale of that work for at least a set period of time. And here, as I will explain next time, things start to get complicated…
