WrestleMania 34 is WWE's biggest show of 2018 in more ways than one. Wrestling's Super Bowl should feature an attendance of around 75,000, lasting somewhere between six and seven hours long. Every single WWE championship will be on the line Sunday night in New Orleans, and 14 matches are expected to be on the card. Below are predictions for every WrestleMania 34 match. A lot has changed since Lesnar and Reigns fought for the world title in the WrestleMania main event three years ago.

Will The Undertaker retire after WrestleMania 33? It's a question many WWE fans are asking ahead of the Deadman's match with Roman Reigns at the biggest wrestling event of 2017. The Undertaker, 52, made his WWE debut in 1990, and he's been the one constant in the company ever since. He has a 23-1 record at WrestleMania, and he's had a match at the PPV in every year since 2001. But questions surrounding the Deadman's age and health have a lot of people wondering if Sunday night could be the last time fans get to see The Undertaker compete in a WWE ring. "He just had hip surgery. He's beaten down real bad. Put it this way--last year when he went to the dressing room after his match, he told everyone he was done," Dave Meltzer of The Wrestling Observer told Richard Deitsch on last week's "Sports Illustrated Media Podcast."

Roman Reigns got his payback on The Undertaker on the most recent edition of "Monday Night Raw." The three-time WWE Champion ended the show by delivering a Spear to the Deadman, and he's now expected to win their WrestleMania 33 match. The Undertaker made a surprise return to WWE, appearing in the middle of the ring during Reigns' match with Braun Strowman. The Deadman delivered a Chokeslam to Strowman, allowing Reigns to attack The Undertaker when his back was turned. Two weeks earlier, The Undertaker hit Reigns with a ChokeSlam and the WrestleMania match was made.

With WrestleMania 33 just a month away, it's been clear for a few weeks what WWE's top superstars will be doing at the biggest pay-per-view of 2017. A match between Brock Lesnar and Goldberg has been confirmed, while The Undertaker is likely to face Roman Reigns. The future of AJ Styles, however, hasn't been as clear. Aside from various rumors, the longest-reigning WWE Champion of the past year didn't have an obvious opponent for WrestleMania 33. The latest edition of "SmackDown Live," however, has provided the spark for Styles' next feud.

It's been three years since "The Streak" came to an end, but The Undertaker's match is still one of the biggest parts of WrestleMania each year. While it hasn't been confirmed that the Deadman will perform at WrestleMania 33, it would be surprising if he wasn't on the card at WWE's signature event of 2017. In the months leading up to WrestleMania, there is always speculation regarding who The Undertaker might face. Following his win over Shane McMahon at WrestleMania 32, The Undertaker's next opponent might not be the WWE superstar that many fans had once thought it would be. Before John Cena underwent surgery in January of last year, he was reportedly supposed to face The Undertaker in front of over 100,000 people at AT&T Stadium.

Following the 2017 Royal Rumble, the WrestleMania 33 match card looks to be falling into place. Brock Lesnar vs. Goldberg has already been made official for the pay-per-view, and a few of the other top matches aren't difficult to predict. There seems to be some uncertainty, however, surrounding the future plans for WWE's biggest full-time performer. With WrestleMania 33 still nearly two months away, Cena's opponent remains unclear. As the current WWE Champion, Cena is in line to face Royal Rumble winner Randy Orton on April 2 in Orlando. That could change at Sunday's PPV when Cena puts his belt on the line against five other wrestlers in the Elimination Chamber.

Amid Japan's rapidly aging population, a burgeoning industry is targeting families expecting a death in the near future. Services on offer range from seminars on funerals and inheritance arrangements to a board game that prepares players for the financial implications of age-related decline. With more and more elderly Japanese living alone, consultations are also offered on how to obtain guardianship needed for time in hospital, as well as how to bequeath assets to individuals and organizations other than legal heirs. Pip Robot Technology Co.'s "Kokorozumori" ("Making Preparations in One's Head") is a dice board game that gets families to think about the costs and implications of caring for aging, ailing relatives. The Osaka-based manufacturer of robot dolls intended as companions for elderly people created the game in 2015, in collaboration with a research team at the University of Tsukuba. Players form pairs -- one elderly and the other a younger family member -- and earn an income in the form of pension and salary as they progress on the board.

Ever since the first vision of a robot appeared on the horizon of mankind, humans have feared that automation will replace the workforce in our dystopian future. There typically follows a period of reassurance, in which we are compelled to believe that this will be a good thing, and that robots could actually liberate us from the drudgery of daily toil and free us for more enjoyable, cerebral pursuits. Futurist Jerry Kaplan, 63, is among those optimists. He estimates that 90% of Americans will lose their jobs to robots and we should all be happy about it. "If we can program machines to read x-rays and write news stories, all the better. I say good riddance," Kaplan said.
