eli5: Why do we always get strong urge to be lazy if its better for the brain to be active

665 views

I mean its so much better for the brain to be active working doing useful things stimulating your brain or working out, we all have a reward system and everytime we finish a task we feel a sense of accomplishment but everytime you should be doing something that you know will feel good in the end you just get this urge of doing nothing today and just relaxing,
shouldnt our brain be chasing this sense of accomplishment? Where does this feeling come from

1. Conserving calories is most compatible with reproducing at high levels.

2. Physical activity should be for a purpose.

3. Going to the gym or etc is not a purpose your lizard brain can get behind

4. You don’t live in a society in which purposeful exercise is part of the lifestyle or daily activities. You probably don’t walk to and from work. Your body would have no issue with you doing that because it is very different from exercise for exercise’s sake

World-class chess players burn about 6000 calories every day.

Using your brain takes energy.

You can watch yourself all the episodes of “naked and afraid”

Buff and stong hyperactive people don’t last 3 days with their hard work. Meanwhile, there was a dude that didn’t even built a shelter, almost slept 21 days straight under a palm and won.

The life saving process is: “is there anything here that’s super easy to do and gives a reward? No? Ok do nothing, save those calories for the right occasion”

Our brain has two system
System 1 and System 2:

System 1 is fast,Intuitive,quick,Emotional
System 2 is deliberate,Logical,slow
Much of our Brain spends some time in system 1
An example of that is: when i ask you 1+1 = 2
Your “system 1” already knows it
When i ask you 57 x 54
You will deliberately look for answers in your brain
So when you spends sometime in “system 2”
Your brain consumes willpower or “glucose” in your brain ,to the point of mental exhaustion
So to take this point
What does it feel when you’re brain is overloaded with information
Many equation ideas sprung
Your nose bleeding

Laziness is not a bug, it’s a feature.

Back in the day laziness stopped people from wasting energy, but now we have steady diets and technology. Our bodies didn’t keep up and try to save energy anyways.

I mean, I get pretty excited after binging a show or finishing my Chinese take out, does that count? 🤤

Human brains evolved to be lazy and do as little as possible while still surviving. Expending excess energy for most of human history has been a waste and would only increase the risk of you dying.

I noticed if I stay home ,all I’ll do is just watch videos ,play games and sleep alot. The next day I’ll be sore from not moving ,my body feels even more tire,so what did I do? I started taking walks little stretchs, 10 minutes my body feels better. My mind wakes up faster. It’s like a lag if we don’t do it. So now I wake up stretch which I learned from my dog and cat, the first thing they do is stretch. Walk a little drink water and stretch more.

I couldn’t sleep for almost a week until I started this routine ,now I sleep like a baby faster and easier than ever before. Even my body is like dam!. We are ready

Being Lazy means not doing things, which is evolutionarily good when Doing Things for millions of years meant “expose self to predators”

Here is the non-theoretical, non-theory-of-evolution practical scientific answer as explained to a 5 year old:

Within the context of being lazy I assume you’re talking about watching TV, playing video games, scrolling endlessly through feeds on your phone etc – your brain releases a chemical called dopamine, and it feels good so you want to do it a lot.
