What are those floaty things in your eye Michael Mauser
Have you ever noticed something swimmingin your field of visioné It may look like a tiny wormor a transparent blob, and whenever you try to geta closer look, it disappears, only to reappearas soon as you shift your glance. But don't go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater. The scientific name for these objectsis Muscae volitantes,
Latin for quot;flying flies,quot; and true to their name,they can be somewhat annoying. But they're not actually bugsor any kind of external objects at all. Rather, they exist inside your eyeball. Floaters may seem to be alive,since they move and change shape, but they are not alive. Floaters are tiny objectsthat cast shadows on the retina, the lightsensitive tissueat the back of your eye.
They might be bits of tissue, red blood cells, or clumps of protein. And because they're suspendedwithin the vitreous humor, the gellike liquidthat fills the inside of your eye, floaters drift alongwith your eye movements, and seem to bounce a littlewhen your eye stops. Floaters may be onlybarely distinguishable most of the time.
They become more visiblethe closer they are to the retina, just as holding your hand closerto a table with an overhead light will result in a moresharply defined shadow. And floaters are particularly noticeable when you are lookingat a uniform bright surface, like a blank computer screen, snow, or a clear sky,
where the consistency of the backgroundmakes them easier to distinguish. The brighter the light is,the more your pupil contracts. This has an effect similarto replacing a large diffuse light fixture with a single overhead light bulb, which also makesthe shadow appear clearer. There is another visual phenomenonthat looks similar to floaters but is in fact unrelated. If you've seen tiny dots of lightdarting about
when looking at a bright blue sky, you've experienced what is knownas the blue field entoptic phenomenon. In some ways,this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windowsletting light through to your retina. The windows are actually causedby white blood cells moving through the capillariesalong your retina's surface. These leukocytes can be so largethat they nearly fill a capillary
Why Do We Kiss
Hey, Vsauce, Michael here. Attachment of two people's lips kissing. The average person will spend about 20,160 minutes of his or her life kissing. And the worldrecord for the longest, continuous kiss is 58 hours 35 minutes and 58 seconds.But why do we kissé I mean, if you think about it, it seems kindof weird.righté I mean, sure, today kissing represents peace, respect, passion, love.But when the first two people in human history kissed, were they just kind of being grosséWell, let's begin with what we do know: kissing feels good and it's good for you.
A passionate kiss burns about 23 caloriesper minute, and releases epinephryn and norepinephryn into the blood, making your heart pump faster.Kissing more often is correlated with a reduction of bad cholesteral and perceivedstress. But these positive effects didn't become widespread by accident. Why did brainsand bodies that love kissing become so commoné Well, a popular story holds it that Pacman'sshape was inspired by the shape of a pizza with a slice missing. But Toru Iwatani, thecreator of Pacman, admitted that this was only halftrue. Pacman's shape was also inspiredby rounding out the shape of the Japanese character for quot;mouth.quot; And it's mouths andPacman's favorite activity, eating, which
together bring us closer to the heart of the kiss. Evolutionary psychologists have argued thatwhat we know today as quot;kissingquot; may have come from quot;kissfeeding,quot; the exchange of prechewedfood from one mouth to another. Mother birds are famous for doing this, and many primatesare frequently seen doing it as well. Not that long ago, it was common between humanmothers and their children. In fact, before commercially produced or DIY babyfood instructionswere readily available, it made a lot of sense. Recently, Alicia Silverstone uploaded a clipof herself mouth feeding her child. It seemed strange to some people, but even though, yeah,it exchanges saliva, which, like any contact
with an infant, can transfer pathogens, healthymothers and healthy children can benefit from the fact that kiss feeding provides nutrients.Carbohydrates, proteins, iron and zinc, which are not always available in breast milk. Plus, an adult saliva can help predigest the food, making vitamins like B12 easier for the baby to absorb. So, mouthtomouth attachment has a historyof intimacy, trust and closeness. Your saliva also carries information about who you are,your level of health, and mucus membranes in our mouths are permeable to hormones liketestosterone, making a kiss a way to tastetest a potential mate. A good kiss can be biologicalevidence that your kisser might be a good mate.
So, as a strategy for mate selection, prehistoricpeople who enjoyed kissing, and did it more often, may have made better decisions, pickedbetter mates, reproduced more successfully, and, eventually, become the norm. Giving us.us,people who love kissing. Any infant could have seen those benefitscoming from a mile away, even though an infant's vision isn't that great. From birth to fourmonths, babies can only focus on things about 810 inches away from their face which, notsurpisingly, is about the distance to their mother's face while breast feeding. So, faces, especially those looking rightat us, tend to be the very first things in
our lives we can focus on and see clearly.This might explain why we are so good at detecting faces. Humans are off the charts when it comesto this, in fact, we tend to see faces even when there aren't any.It's called quot;pareidolia.quot; Because humans are so cooperative, it makessense for us to be good at recognizing faces. And, more importantly, detecting when someoneis looking directly at us and clearly expressing when we are looking at someone else. A predator who lives by not being seen needsa gaze that's less obvious. In fact, research has shown that our surprisingly white scleras,the area that borders the iris, isn't just
