The Importance Of Television

Fire is considered one of the most important discoveries in the history of our species. Since the dawn of time, it has provided us with warmth, light, cooked food and the power to invent even more things.

We can see how important fire was to our ancestors from how integral it was within a house.
In prehistoric times, there would always be a fire at the centre of a cave or hut, where the family could gather around for warmth and light. Here, they would warm themselves on a cold winter’s day and cook meat that they hunted during the day to tenderise it.

Unlike the old days, we no longer have open fires in the house. Instead, fire has been split into three different forms.

  • Instead of huddling around an open fire for warmth, we have boilers and hot water cylinders to warm our houses.
  • Instead of cooking our food over a campfire, we have gas or electric stoves and ovens.
  • Instead of the flickering flames providing us with light and distraction, we have television and computers.

Of course, we still have fireplaces, barbeques and candles, but the modern person tends to rely more on modernised versions of fire.

An interesting takeaway from this theory is how television is the modern form of the psychological comfort that fire provided us. In prehistoric times, people would struggle to stay alive, running from predators and hunting to feed the family. Looking at the fire mindlessly at the end of a hard day’s work would have been a way to destress and unwind.

Nowadays, most of us are lucky enough to not have to fear death on a day-to-day basis, but we still suffer constant stress from the busy modern life. Perhaps sitting in front of a television or computer to procrastinate for half an hour is not the worst thing in the world.

That said, everything should be done in moderation. It is good to relax for a set amount of time, but if you spent every evening after work staring at a screen without an original thought, your mind will dull and atrophy.

So, it is good to balance out the mindless entertainment such as comedy or reality shows with films that provoke thoughts and emotions, documentaries that provide you with knowledge, and shows that stimulate your creativity.

Most importantly, what you think and feel and learn after watching these should act as fodder for conversations that help deepen your connection with other people.

Shared Bodily Warmth

Body heat is a vital condition that animals need to survive. It is so vital that when you are hypothermic, your body will override almost everything else to conserve heat as much as possible. Without enough heat, the chemical reactions that fuel your cells will grind to a halt and you will die. To solve the issue of getting heat, nature came up with two answers: endotherms and ectotherms.
Endotherms are organisms that produce their own heat (e.g. mammals) by trapping the heat produced by metabolism and through extra mechanisms such as shivering. Ectotherms rely on absorbing environmental heat (e.g. reptiles), usually through the sun. Because of this, ectotherms suffer a much greater range in body temperature. This means that animals such as lizards will be slower and more sluggish when it is cold.

Being in a cold environment quickens the process of heat loss, robbing you of the precious heat you generate. A solution to this is shared bodily warmth. Also known as kleptothermy, this is a common thermoregulation strategy where a group of animals huddle together to share the heat generated by each other. This increases the efficiency of heat generation (thermogenesis) and the group as a whole can stay warmer for longer. This behaviour is commonly seen in communal animals such as mice, who huddle together even when they are newborns (newborns lose heat much quicker than adults due to the difference in weight to surface area ratio). Some ectotherms such as snakes and lizards also engage in kleptothermy, where by huddling together they increase their effective mass and reduce heat loss.

An interesting case of kleptothermy is seen in Canadian red-sided garter snakes, where the heat is not shared, but stolen. A male snake will sometimes emerge from hibernation and begin to produce fake pheromones to attract other males as if it were a female. Other males are fooled into thinking that the snake is female and approach it to mate. Through this strange process, the snake is able to steal the heat from its rival males and use the extra energy to mate with an actual female (or lose it to an even more cunning male snake).

Hedgehog’s Dilemma

Imagine two hedgehogs in the middle of winter. Even though they wish to huddle together to keep warm, they must keep distance to not become stabbed by the other hedgehog. There is no way they can avoid hurting each other without keeping their distance. Although both hedgehogs badly want to be close and intimate, they cannot. Therefore, the hedgehogs sacrifice the potential warmth for their own comfort.

Human relationships are just like the hedgehogs in the allegory. If a relationship is too close, the two people have a serious danger of hurting each other in one way or another. It is crucial to find the balance between keeping distance and having enough intimacy to have a good relationship, but much like the hedgehogs, this is a very difficult task. 

Some people may have the unfortunate experience of being pricked by another hedgehog and learn that getting too close hurts too much. These people try and keep their distance from other people and rely on their internal warmth to not freeze during the winter. This phenomenon is more pronounced in introverted people and clearly seen in those suffering from social anxiety.

This is the dilemma of the hedgehogs: should one sacrifice the warmth of companionship to avoid pain? Or should one overcome the potential pain to attain the intimacy that we all seek? Figuring out where the perfect balance lies and respecting each other’s personal space is quite possibly one of the most important factors in having a healthy relationship.
