 why do we clink glasses and say cheers

why do we clink glasses and say cheers

ItБs not something we spend much time thinking about. You toast one another, you БcheersБ, you clink glasses, and then the rest is (often forgotten) history. But why do we clink glasses while staring into each otherБs eyes. And what exactly has toast got to do with anything? Well, apparently, the custom of raising a glass to one another before drinking originated with the Romans and the Greeks (surprise, surprise), who used to offer wine to their gods before celebrations. The expression Бto toastБ, meanwhile, does actually come from the practice of putting a piece of toast in your drink. It was something people did in Elizabethan times to improve the taste of wine Б the bread soaked up some of the acidity in poor wines. ...

why is cranberry juice good for a uti

Life is never reallllllly the same after your first UTI, right? That one-two punchвthe burning sensation when you pee, chased by the urge to pee again approximately six seconds after you flushвsears itself in your memory. Years after your first UTI, you'll be sitting in a meeting wanting to pee, realize you just peed 20 minutes ago, and although you really don't have a UTI because you would know, you connect the timeline dots and the anxiety creeps up in your throat: omgdoihaveauti? For the who experience them, UTIs are mentally scarring like that. Total dread inducers: painful, uncomfortable, and mind-consuming things that gnaw at you until they're treated properly. Of course, if left untreated, they can turn into much more serious kidney infections, but (thankfully? ) they're so

 why do we have blind spots in our eyes

why do we have blind spots in our eyes

Our eyes have a blind spot for a very good reason. On the back of our eye, the retina is the stuff that detects the light. All the information that the retina picks up is sent to the brain through the optic nerve. The only problem is that the optic nerve needs a way to get out of the eye. The place where it leaves is where we have our blind spot. Since we have 2 eyes that can move around, we don't notice the blind spot often. Here's an interesting way to see your blind spot. First, take a piece of paper and draw 2 small dots on it. Cover one of your eyes. Hold the paper so the dots are on the same level (parallel to the ground). Stare at one dot and slowly move the paper towards and away from you. You will see that the other dot will disappear. That is the dot in on your blind spot and

why do we get bags under eyes when tired

Been burning the candle at both ends like Effie? (Picture: Channel 4) ItБs a day of the week so weБre feeling a little fatigued. And weБre already battling those pesky dark shadows under our eyes. But why do we get dark circles under our eyes when weБre knackered? First up, itБs important to note that dark circles and eye-bags are two separate things, although they often appear in tandem. Dark circles Dark circles are down to genes as much as lack of sleep. The skin underneath your eyes is thin and covers muscles, fatty tissue and blood vessels. Dark circles are the result of light being reflected back from blood vessels sitting just below the skinБs surface. How dark that area is has a lot to do with skin colour and thickness. As to why theyБre more prominent when youБre tired, itБs

 why do volcanoes occur at constructive plate margins

why do volcanoes occur at constructive plate margins

There are a number of different types of plate boundary. A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate A section of the crust that makes up the Earth's landmasses. Friction causes melting of the oceanic plate and may trigger earthquakes. Magma rises up through cracks and erupts onto the surface. An example of a destructive plate boundary is where the Nazca plate is forced under the South American Plate. ...

 why do we need a standard system of measurement

why do we need a standard system of measurement

Imagine you are trying to find out how much an elephant weighs. You are pretty sure it weighs a lot, but you don't know the exact number. So you ask your teacher, and she tells you an elephant weighs the same as three hippopotamuses. Well that's nice to know, but how much does a hippopotamus weigh? Again, you ask your teacher, and she tells you a hippopotamus weighs the same as five alligators. That's a cool fact to know, but you still don't understand how much an elephant weighs because comparing elephants to alligators can be confusing. To avoid confusion when measuring, scientists use a shared system of measurement, called the International System of Units (SI). 'Unit' is the word used to describe how something is measured. ...

 why do you put salt in coffee

why do you put salt in coffee

Salt enhances flavors. The magic of salt is that it unlocks already-present flavors, making them stand out. In essence, it makes food taste more like itself. This is why we put it in pretty much everything we eat, including sweet things. Some people find that a touch of salt will bring out interesting flavor notes you wouldnвt otherwise notice in your morning cupвalthough sometimes, those characteristics may only serve to make you realize that you need to buy better coffee. Salt improves the water. People are fond of saying that your coffee is only going to be as good as your water. If you have hard water or the water you are using to brew coffee is less-than-fresh because itвs been sitting in your coffee makerвs reservoir all night, your coffee might end up being subpar. However, if you

why do you think the conservation of wildlife is essential

There are a lot of wonders in the world and among them are wildlife species, such as bears, mountain goats, wolves, elk, and deer.
