What is anaesthesia? Anaesthesia is a medical treatment that keeps you from feeling pain during procedures or surgery. The medications used to block pain are called anaesthetics. Different types of anaesthesia work in different ways. Some anaesthetic medications numb certain parts of the body, while other medications numb the brain, to induce a night of sleep through more invasive surgical procedures, like those within the head, chest, or abdomen. How does anaesthesia work? Anaesthesia temporarily blocks sensory/pain signals from nerves to the centres in the brain. Your peripheral nerves connect the spinal cord to the rest of your body. What are the types of anaesthesia? The anaesthesia your healthcare provider uses depends on the type and scope of the procedure. Options include: Local anaesthesia:  This treatment numbs a small section of the body. Examples of procedures in which local anaesthesia could be used include cataract surgery, a dental procedure or skin biopsy. You’re awake d

Now let's talk about wants and needs. Needs are really important items like water, protection, clothing and food are some of the necessities in life. Wants are the luxuries that arent needed but you want them and you would probably have a really big wants list, a list that's bigger than the necessities list. here is where we come to the scarce resources part. Everyone wants infinite things when there are finite resources, how is this possible? Unlimited wants + limited resources = Scarcity Resources are finite - they are only as valuable as they can be put to use by humans. If a resource is not used, then its value decreases over time until it becomes completely worthless (elements such as uranium ore). It is a basic human trait to never be satisfied, but in the end, we are going to need to be satisfied. There are many ways that people deal with scarcity, including trading with other individuals who have more resources than they do. The most common method is to adopt a mindset

20 years ago, most of us didn’t have cell phones. 15 years ago, it was rare to carry a smartphone. With the proliferation of today’s smartphone technology, we take it for granted that we can make and change appointments, access the world’s information, map our locations, and much more in the palm of our hands. What happened to transform phones from static devices—and the occasional car-mounted monstrosity—into the sleek supercomputer-in-your-pocket that we have today? Smartphone history deserves a bit of introspection, as it represents a seismic shift in our society. The First Smartphone: 1992 Fast-forward nearly 10 years later, and IBM debuted the “Simon” personal communicator, a device that featured an early touchscreen, and the ability to send and receive emails and faxes, act as a pager, and perform other smartphone-like functions. It was available in mid-1994, at a price of $1099 without a contract. Interestingly, this is the same as the list price of a base model iPhone 13 Pro Ma

  History of Vaccines Vaccines have revolutionized global health, eradicating viruses like smallpox and nearly eliminating poliovirus - diseases that previously killed millions of people. The number of people who contract preventable infectious diseases like measles, diphtheria and whooping cough is at an all-time low, thanks to vaccines. What is vaccination? Vaccination is a simple, safe, and effective way of protecting people against harmful diseases, before they come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger. Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications. Most vaccines are given by an injection, but some are given orally (by mouth) or sprayed into the nose Dise
