There are allegedly five people left who lived during the 1800s, according to the Gerontology Research Group, which tracks the oldest living people on earth.
They are all women, most are relatively active, and they have all been kind enough to share their secrets to a long life with the internet.
Get ready for the next lifestyle trend to be a strict regimen of bacon, bowling, grappa, and lingerie:
Susannah Mushatt Jones is 115 and lives in New York, and eats bacon every single day.
"I have no secret," Mushatt Jones told Time in a video interview back in July, but says she just has a lot of things she loves. One of these things is bacon — four strips a day with eggs and grits. She sometimes saves one strip in her pocket for later.
She also loves lingerie. Her niece recalled: "One time, when she had to get an EKG, the doctors ... were surprised to see her wearing lingerie, and she said, 'Oh sure, you can never get too old to wear fancy stuff.'"
Michigan resident Jeralean Talley is 115 and tries to treat others how she'd like to be treated.
Talley is allegedly the second-oldest person in the U.S., born in May 1899. She hails from the South but now lives in Detroit with her daughter.
She told the Huffington Post that her main secret to a long life is an age-old rule: "Do unto others as you would have them do unto you, that's my way of living."
Emma Morano-Martinuzzi is 115 and lives in Italy, and one of her secrets to a long life is eating a raw egg every day.
115-Year-Old Emma Morano From Italy, The Oldest Person In Europe (Born On November 29, 1899)
Morano-Martinuzzi was born in November 1899, just a month before the end of the 19th century, and is reportedly the oldest person in Europe.
She told La Stampa that her secret to a long, independent life is one raw and one cooked egg daily (diet advice a doctor gave her when she was 20), pasta and minced meat for lunch, and a glass of milk for dinner. Not to mention 11 hours of sleep a night and the occasional glass of grappa.
Arkansas resident Gertrude Weaver is 116 and loves to wheelchair dance.
Weaver is allegedly the oldest woman in America, born in 1898. She celebrates her birthday, appropriately, on the 4th of July, and loves "wheelchair dancing and manicures," Time reported.
She has the same piece of long-life advice as Jerealean Talley: "Treat people right and be nice to other people the way you want them to be nice to you."
Misao Okawa is 116, lives in Japan, and thinks eating is the key to happiness (don't we all).
Okawa is the oldest recorded human in the world, and was reportedly born in Osaka in 1898. When she was told she was 116 on her birthday, she laughed and said, "I could never expect to live that long!" and later added, "It was kind of short."
She told the Daily Telegraph that you should "[e]at and sleep and you will live a long time. You have to learn to relax."
She eats three large meals a day and particularly enjoys sushi, especially mackerel on steamed rice.
Who run the world? Wise old biddies.
Misao Okawa was born in 1898. An earlier version of this post misstated her birth year.
