    Hey guys,
    I got my brain entangled...thus I am confused.
    Here is the reason why:

    Let's say I don't have the healthiest customs.
    And let's say my heart suffers from it.
    If this happens, high blood pressure and heart problems can be the consequence.
    Okay...
    -The brain controls all the functions in our body.
    -So does the brain control our blood pressure and heart rate.
    -The brain "tells" the organs what to do.

    Now my question:
    If we get sick by smoking or drinking too much alcohol, or being too fat, or whatsoever may be there because of laziness or other vices, why does the brain not simply "tell" us not to smoke anymore or not to drink anymore and do more sports?
    I mean...that we just quit automatically these negative customs so our survival is protected?
    Why does our brain not always tell us what is "right"?
    So that there is no other possibility for us to engage in a healthier lifestyle, because we FEEL like it?

    Why are we able to destroy ourselves, while this is completely illogical to do just that?


    I am.
    You can't deny it.

    simple reason: Free will and the ability to choose

    Well, unlike other functions in your body, those are voluntary actions you're talking about. I'm not an expert on the subject, but I would presume that this is the primary reason why your CNS won't object. However, I would also presume that the body tells you to stop what you're doing when it starts rejecting the foreign materials in your system, ie. vomiting when drinking too much, coughing when smoking more than you're supposed to, or growing large when you excessively eat.

    The body does the minimun it needs to in order to keep you alive via involuntary functions - the rest is up to you.

    Well think about it differently,
    if you get hungry; you eat,
    if thirsty; you drink.

    Although you claim to have voluntary control over each, I doubt you have ever decidedly stopped eating/drinking permanently!
    Smoking, being an addictive habit becomes the same; it becomes a need and it is very difficult for the brain to switch off what becomes almost instinctive.
    the brain in a way satisfies its own needs before considering other organs! Has anuyone ever said to you "smoking is bad for you" and you decidedly put it out there and then; probably not (I dont know if you smokee, but its jst an example). You (your brain) decides to instead satisfy the nicotine craving first.

    There are various hierarchies in the brain (depending on the region) and there are things over which you have no control (eg heart), things over which you have partial control (eg breathing; you cannot decide to stop breathing and kill yourself) things where there is an intermediate balance (perhaps like your smoking) and then things over which you have total control, eg your movement).

    as for killing yourself, humans fare one of the only species (the only?) which can decide to kill themseklf so I am not sure as to what the process there is.

    A lot of the things you're mentioning have only become problems in very recent human history - evolutionarily speaking, of course. Ancient humans and some of the hominids before them may have done something similar to smoking, they may have had some kinds of fermented drinks, but they probably didn't do it to the extent we do today, and at the time they were much more likely to die from disease, predators, or the elements. And extra excersize was something they probably didn't need - just surviving was challenge enough.

    Only today do people seriously suffer from these habits. There hasn't been time for us to evolve ingrained negative reactions to them. It is possible - some birds instinctively avoid certain snakes even having never seen them before, having evolved to stay away from these poisonous predators. All the birds who did not stay away died, and took their genes with them.

    It is also possible we may never evolve instinctual avoidance of these behaviors. As long as the people who don't smoke and the people who do smoke both reproduce equally well, there will be no incentive against it. What does it matter if the smoker dies earlier? Or if a lazy overweight person dies of a heart attack? As long as they reproduce before they die, their genes will still be carried on.

    The best thing humans can do right now is learn to control themselves. It is an ability we above most if not all other animals have, and it is part of what has made us so dominant on the planet.
