    Smelling is a quite "straightforward" sense, as we are actually inhaling tiny particles of the substance smelled. They hit the olfactory epithelium, the mucous membrane in the nasal cavity, containing millions of olfactory receptors. These sensors interact with the particles and send signals to the olfactory nerve, which sends them to the brain.

    Is hookah hazardous? Hookah smoke is extremely dense and contains the same high level of carcinogenic substances as cigarette smoke. Even if you do not smoke and just pass by a hookah shop, you can get an impressive dose of carcinogenic substances in 3 minutes and have the same risks as smokers. Moreover, during one hour of hookah smoking, a person inhales an amount of smoke 200 times more than from a single cigarette! Besides, when hookah smoking, cold fumes enter the body, which doesn't have time to turn on the protective mechanisms in the respiratory tract - the production of antibodies and immune factors. Thus, harmful substances enter the body instantly. Cigarette smoke is hot, and the defense mechanism kicks in faster.

    Unlike arm and leg muscles, cardiac musculature doesn’t get tired and need no rest. Imagine lifting a dumbbell 100,000 times in one day – unbelievable! Other muscles tire quickly, need rest, and ache if we give them an extra load. Still, the heart is pretty clever: it beats at various speeds in different circumstances.

    The way we lose nerve cells from birth How many neurons (nerve cells) exist in the human brain? We have roughly 85 billion of them. By comparison, a jellyfish has only 800, a cockroach only a million, and an octopus 300 million. Most people believe that nerve cells die only in old age, but the bulk of them are lost to us in childhood, when in the child's head occurs the process of natural selection. As in the jungle, among the neurons, the most efficient and adaptable ones survive.

    How does our gut recognize which bacteria are good and which are bad? That’s a pretty tough question, and it depends on the receptors. Toll-like receptors recognize what are called molecular models of bacteria. Pathogenic bacteria have separate models, so the cells determine that such a bacterium is various from the one that should inhabit us. They are resistant to "friends" (good bacteria) and live with them in symbiosis. The presence of the "enemy", in turn, causes anxiety and activates the immune system.
