[Music] it's um sometime what if everyone became a baby again no big deal um some is already a baby oh I'm some if everyone became a baby again bosses will have no option but to do all the work now huh we may start hearing baby crying noises from everywhere um we may start fighting over toys again hmm we may have to learn how to walk again we may not be allowed to use mobiles anymore we may not be allowed to watch late night television anymore [Music] we may have to switch back to drinking milk
from a baby bottle hmm even superheroes will become babies now instead of gold thieves may start stealing candies hey hmm even aliens may start experimenting on themselves to become a baby again [Music] hmm to buy um some merchandise visit umsum.com what if you fall into quicksand no problem I am quicker than quicksand oh I'm some quicksand is a waterlogged mixture of sand clay and salt [Music] it is a non-Newtonian fluid that is it changes its thickness or viscosity depending on the stress appl
ied on it so an undisturbed quicksand appears and acts like a solid but when we step on it our weight increases the stress hence it starts behaving like a liquid thus causing us to sink however we will not fully sink into quicksand why firstly because quicksand is usually not very deep secondly It is believed that quicksand is a bit denser than humans so what in an experiment experts prepared aluminum beads which had similar density as humans oh when they placed those beads in quicksand and move
them to mimic the action of a panicked human the Beats sank but only halfway thus indicating that we will not completely sink in quicksand what is sleep apnea the ability to sleep 24 7. no sleep apnea is a sleep disorder in which breathing is repeatedly interrupted during sleep there are three types of sleep apnea first is obstructive sleep apnea in which the muscles and soft tissues present at the back of our throat relax and collapse blocking the breathing passage and thus preventing the inha
led air from reaching the lungs second is Central sleep apneon which our brain fails to send appropriate signals to the muscles that control breathing now although the breathing passage is open the muscles don't perform their tasks hence breathing stops third is mixed sleep apnea in which a person suffers from obstructive sleep apnea as well as Central sleep apnea now in all the above three types lack of oxygen and shortness of breath trigger our brain to wake us up from sleep so that we can sta
rt breathing again how do hormones work they are lazy like me not at all in our body there is an endocrine system which consists of several glands these glands secrete various hormones and release them usually into the bloodstream now our cells have specialized receptors on them a hormone will attach only if there is a receptor for that hormone ensuring that just the target cells get stimulated when the cells get stimulated specific processes in the cells increase or decrease thus helping us reg
ulate our heartbeat blood pressure body temperature sleep Etc thus maintaining our health for example if blood sugar level drops pancreas will secrete a hormone called glucagon glucagon will attach to receptors of liver cells and instruct them to convert stored glycogen into glucose thus increasing our blood sugar levels thus hormones are super important for our body what is gigantism it's the nickname of my friend the Great Hulk in our brain a pea-sized structure called the pituitary gland prod
uces growth hormone helping regulate and increase our height girth weight Etc however in some rare conditions a non-cancerous tumor in the pituitary gland can trigger it to produce far more growth hormone than the body requires leading to a large tall stature and thus causing gigantism one example of this condition is Igor volkovinsky the current tallest man in the United States his height is 7 feet 8.33 inches according to experts in such cases the internal organs might become much bigger than
their normal size however on the flip side gigantism may lead to deformities in the muscles and Bones making it difficult for the person to perform daily tasks like walking running Etc hmm which is better hot shower or cold shower no shower is the um some Mantra so gross let's have a look at the advantages of cold showers first as we are warm blooded the sudden sensation of cold water awakens our body thus making us feel fresh and alert secondly many scientists believe that when our body suddenl
y comes in contact with cold water it sends a jolt of electrical impulses to our brain helping boost our mood in the process lastly cold showers May contribute to weight loss as our body might burn more fat to generate Heat hot showers have the following advantages firstly scientists believe that hot showers lead to the release of a hormone called oxytocin easing anxiety and stress secondly as hot showers can help clear the nasal passage they might be beneficial for a person suffering from cold
thirdly hot water can help release tension and stiffness in our muscles lastly hot water can kill bacteria thus preventing infections hmm what causes swelling dreaming about balloons causes swelling now swelling or edema usually occurs when tiny blood vessels leak fluids into the surrounding tissues some causes of Edema are as follows firstly our liver releases a protein called albumin into the bloodstream albumin keeps fluids from leaking out of the blood vessels however in a serious liver cond
ition called cirrhosis it cannot produce enough albumin without albumin our body can't prevent fluids from leaking thus causing swelling secondly in nephronic syndrome the filtering parts of kidneys called glomeruli get damaged causing excess loss of proteins like albumin thus leading to swelling thirdly growing uterus can put pressure on the veins present in the legs of pregnant women causing blood to pool gradually forcing fluids to leak and thus causing swelling however not all swelling is ba
d because during an infection excess fluids and immune cells reach the infected site to fight germs this can also cause swelling but in this case it is good for our body why do we shrink with age cause we want to become Ant-Man no there are various reasons behind this firstly our spine consists of fluid-filled discs placed in between Bones called vertebrae but as the years pass by these discs begin to lose fluid and degrade causing them to flatten as a result the distance between the vertebrae d
ecreases thus decreasing our height and making us shorter secondly as we age many of us suffer from osteoporosis this makes our bones so weak that they develop micro fractures now as most of these fractures happen in the front of our vertebrae it causes forward rounding of our back a condition called kyphosis this gives us a stooped posture thus making us look shorter lastly as aging also causes loss of muscle mass especially in the abdomen it can make a slouch hence this can also lead to a stoo
ped posture thus giving us an appearance of being shorter [Music] workout when we have cold we should just chill and have milkshakes you wish yes one may work out but for shortened duration and with reduced intensity if symptoms are above the neck as in common cold stuffy nose sneezing or jaw pain as these symptoms are minor one can take appropriate cold related medicines and then put in mild exercise with proper care note that light or moderate physical activity may help open up the nasal passa
geway thus helping us feel better but on the flip side there is a chance of spreading germs or viruses to others on the other hand if the symptoms are below the neck as in Fever vomiting cough shortness of breath Etc then one should not exercise our body needs rest in this case hence one should not overwork as it will make it difficult to recover and may also lead to fatigue or dizziness [Applause]
