In today's interconnected world we humans work with tekkie gadgets for hours and hours upon end each day.

What is the Bladder? The organ that we have in the lower abdomen is called a "bladder". This is the organ where urine (made by the kidneys) is collected/stored for later excretion. The collection of urine allows the bladder to expand like a balloon. When the bladder fills up and reaches its maximum capacity, the wall of the bladder contracts. This action is easily controlled by adults with regard to the timing, hence why infants (and in some cases, older people) can’t control when they urinate. When ready to let go, the urethra relaxes and the urine is excreted from the bladder. Then the urine slowly flows through a narrow tube and is excreted out; this procedure in total is called urination. Bladder cancer is when the normal cells go through a lot of transformation, growing and multiplying without any control. When these cells multiply and form like a group it is called a tumour. This tumour increases in size every time there is an addition of cells. The increase in si...

What follows are the most common mental health problems Americans face. Phobias About 2.2% of phobia sufferers are diagnosed with agoraphobia, the fear of open spaces.

The parallelogram and triangle of forces Resultant force             When two or more forces are acting together at a point it is always possible to find a single force which will have exactly the same effect as these forces . This single force is called the resultant force .           Where a number of forces are all acting in the same straight line, the task of finding their resultant becomes simply a matter of addition or subtraction . Thus, if forces of  7, 5, 3 and 1 N act at a point P as shown in the image, we have, Resultant force Forces acting in the same straight line: Total forces acting towards the left = 7 + 5 = 12 N Total forces acting towards the right = 3 +1 = 4 N resultant force          = 12 – 4 = 8 N acting towards the left .

The idea of going for a 2-mile jog probably does not excite you. It is not something many people do on a regular basis. Unfortunately, many people also do not take a simple walk around the block, play a game of ball in the park or do any more activity than necessary. The human body was not designed to sit still all day long. Internal things start to slow down when you do. It is time to get up, get moving and get healthy. Start Slow You do not have to go out and buy all kinds of exercise gear to get started. If you do not have a comfortable pair of walking shoes, you should probably go get a pair of those. If you have not been active in a long time, your joints ache when you move or you lose your breath going up a single flight of stairs, start slower than slow. At this point, anything you do is more than you were doing and is good for you. The next time you go to the grocery store, park at the far end of the parking lot. You will be doing a lot of walking in the store, but you are u...

So much of our communication with each other is done through the computer, cell phones, and text messaging. Technology has enhanced our abilities to connect with one another, and lots of us prefer it to more traditional means of communicating.

Most of us are fascinated when we hear about parallel universe theory.  Is it possible to have parallel universe?  This is the first question that comes to the mind of a common man who hears about the theory of parallel universe.  We have not yet explored one universe and now we are talking about many universes. Though parallel universe theory is new it cannot be ignored as rubbish.  Today there are no concrete proofs like the images of the other planets but then few hundred years back we were not ready to accept the full picture of our own universe too.  We are still not completed the research on the universe and in that research we can always go ahead with new theories and new concepts. Many people think that it is just a figment of our imagination but we do have some people who believe in the theory as they have come across such kind of experiences.  Past life regression is one such experience where people might have experienced the parallel universe....

You’d think that the answer to the question “What dress size are you?” would be straightforward. Most of us know what sizes to grab off the rails when shopping for a new outfit, so why is it that the same size can vary so much from store to store? We’re All Getting Bigger In the last 50 years, the shape of British women has changed beyond all recognition and these changes are mainly due to better diets and better access to healthcare. We’re taller than ever, and the average waist size has expanded too. In the 1960s the average waist size was 27.5 inches and it’s now 34 inches. There have been similar increases in the sizes of bust and hip measurements. It’s an often quoted fact that the average British woman is now a size 16, and many clothing manufacturers have started producing larger clothes to take account of this fact. Just to Make You Feel Good? Stores know that we women like the adrenaline rush and good feeling that we get when we squeeze ourselves into a size smaller th...
