Is all good, but I still appreciate cash:

Me, "You can relax. I am pretty sure cash isn't going to go away. There are many uses that cash just won't be replaced by. And of course there are the people who got buried by huge credit card bills and want nothing to do with credit card companies and their cell phone apps. Cash will always be necessary because what happens if your cell phone runs out of power and you're at a restaurant with your date. Or, someone hacks your phone? and steals your monetary info? When was the last time your cash got hacked? Stolen? Maybe, but hacked? No. So, don't worry. This new way of paying will be like credit cards another form of payment but cash will still be around."

From article, "The $200 Billion Technology That Will Replace Your Wallet

(Smart-chip credit cards are so 2015.

In 2016 and beyond, mobile phones will become the hot new way to pay for goods at retailers, and the number of people who use such technology is set to explode.

U.S. consumers are projected to spend nearly $9 billion buying goods in-store via their smartphones this year, but that number will jump to more than $27 billion the following year, and pass $200 billion by 2019, according to a new report from eMarketer.

The average user will spend about $375 this year via in-store mobile payments, but by 2019, he’ll spend more than $3,000 that way.)

Eating 300 Oranges Stops Cancer?

Me, "People should not get too excited because only certain types of cancer can be treated and you would need doses that are as high as eating 300 oranges a day, so it would probably have to be given to you as an injection, or pill but, its great to know that something as common as Vitamin C can be very beneficial to humans. This has only been shown to work on mice. But could it work in humans? The research continues. These studies are very important because it shows that everyday fruits and vegetables in a well rounded food diet (you gotta get some kind of protein either from meat, or fish, or protein in Tofu) is the right way to eat. It all comes down to: what we put in our bodies is how our bodies will respond."

From article, "Extreme dose of vitamin C destroys mutated cancer cells

(In a stunning breakthrough, scientists have destroyed mutated cancer cells in mice with high doses of vitamin C.

A shocking new study reveals that there may be a new tool in the battle against cancer, and it’s surprisingly common. According to a report from Science Magazine, researchers have found that vitamin C can in fact kill tumor cells in mice that carry a deadly mutation, confirming decades of speculation about the benefits of vitamin C.

It wasn’t until Jihye Yun, a graduate student at Johns Hopkins University, discovered that colon cancer cells carrying a mutation in the genes KRAS or BRAF produced large amounts of a certain protein that transports glucose through the cell membrane, that vitamin C treatment seemed viable once again. The glucose transporter in the cells, GLUT1, was found to also carry the oxidized form of vitamin C, or dehydroascorbic acid into the cell. This was extremely effective at stopping the cancer cell from producing a chemical that consumes free radicals. By flooding the cancer cells with DHA, they became vulnerable and easier to kill.

According to Lewis Cantley, a researcher at Weill Cornell Medicine in New York City, large doses of vitamin C were found to kill cultured cancer cells with the BRAF and KRAS mutations. The vitamin C raised the overall level of free radicals inside the cell, shutting down an enzyme that was needed to metabolize glucose. This deprived the mutated colon cancer cells of energy, leading to their demise. The doses of vitamin C were extremely high – roughly the same as eating 300 oranges.

The researchers are looking to begin clinical trials that will target cancer patients with KRAS or BRAF mutations. High doses of vitamin C are safe, but doubters fear that the results will not be replicable in humans. Treatment would need to occur every few days over the course of a few months, but Cantley hopes that one day a pill form capable of delivering a high enough dose will be available.)
