In 2017, Uber unveiled a tip feature on its app to allow customers to leave their driver a tip. It turns out many customers do not leave a tip. According to a study conducted by Bharat Chandar, Uri Gneezy, John A. List, and Ian Muira with the University of Chicago, only about 16% of rides end with a tip. The study also found that 60% of Uber customers never tip, while 1% always leave a tip. List's study included 40 million trips in the cities of Chicago, Boston, San Francisco, Salt Lake City, Asheville, North Carolina, and Bloomington, Indiana.List's study found the average of those who do tip is .11, about 26% of their fare. The survey found that customers were more likely to tip between 3 to 5 a.m., as well as around 6 p.m. on Fridays; that female drivers, especially younger females, were more likely to earn tips; and that 5-star drivers were twice as likely to earn a tip as a 4.75-star driver.So should you tip? That is up to you, but know that according to the 992

KANSAS CITY, Mo. -- This time of year, it's easy to overspend on gifts for friends and family, but sometimes it's the gift of a handwritten card that can be the best one of all.Annie Taylor visited Hallmark, the world's top greeting card maker, to learn more about the art of this century-old gift.Amy Goodnow is among those who know how special cards can be. Every holiday season, she remembers her dad by pulling out the cards she once wrote to him.“We were a big card sending family,” said Goodnow. “I had it instilled in me from a very young age to write thank you notes for everything.”Now that she has a daughter of her own, every Christmas they've made it a tradition to send greeting cards to friends and family.They’re not alone. About 1.2 billion cards are sent every holiday season."Greeting cards date back hundreds of years," said Samantha Bradbeer, the keeper of the vault at Hallmark, where cards from every decade are kept. "It was popularized under Queen Victoria during her reign in the 1830s."One of Hallmark’s senior writers, Kat Stano, says sincerity is key to crafting a good holiday card and remembering that everyone’s Christmas is different. "You want it to be honest,” said Stano. “You want to think about people’s current life situations and what they are going through."Geoff Greenleaf, one of Hallmark’s most famous artists, tries to encompass the classic American Christmas with each card he paints. "I grew up in Massachusetts,” said Greenleaf. “I just love the winter and find it’s a beautiful time of year."His paintings begin with intricate sketches."The way you can draw people in with a road or going home, there's a lot of emotion around that," Greenleaf said. Greenleaf’s art has been so well received, it became the inspiration behind Hallmark’s Christmas movie, “Evergreen.”If you’re looking for a gift that creates a lasting memory, Goodnow suggests giving a handwritten card. It might be the best way to show someone you care. 1981

If you're a healthy older adult looking for ways to reduce your risk of heart attack and stroke, don't turn to that age-old standby: daily low-dose aspirin. It's no longer recommended as a preventative for older adults who don't have a high risk or existing heart disease, according to 297

Imagine going to a concert or sporting event and not having to wait in long lines to get inside or even having to carry things like your ticket or wallet. Those enhancements to the fan experience are exactly why Mary Haskett and her business partner created Blink Identity. "We developed a sensor that can identify people using biometric face matching at full walking speed at any light, even in total darkness," Haskett explains. Blink Identity was demonstrated at the KNOW Conference in Las Vegas, where dozens of startups specializing in identity technology featured new products. Here’s how it works: First, users register their information, like name and email address, on Blink Identity’s website. Next, users take and upload a selfie of themselves. The photo is then put into Blink’s database. The next time that user goes to an event, the facial recognition technology scans the user’s face and gives the green light to go in. If the scanner does not recognize the person, a red light appears and an alert sounds, letting security know that person isn’t authorized to enter. The technology will cut down on ticket scams and scalpers. Scalpers won't be able to buy tickets in bulk and jack up the prices, because there's no face registered to the ticket. This technology will also spot fake tickets, too. Blink is still testing the technology, but they are working with Live Nation to try to bring this technology mainstream. "The whole concept is to get rid of the piece of paper to get rid of the barcode and let your face be your ticket," Haskett says. Blink Identity hopes one day customers will be able to link their credit card and driver’s license to their account, so they can go wallet-free. 1724
