When you think of beauty-related Guinness World Records, those unbelievably long, curly fingernails probably come to mind. But forget everything you thought you knew: The actual wildest body-part-related record definitely goes to the world's longest eyelashes. They're almost 5 inches long and took their owner nearly 50 years to grow. NBD.

According to the Guinness World Records, You Jianxia of Shanghai, who was born in 1968, has a lash on her left upper eyelid that measures a whopping 12.4 centimeters (about 4.88 inches). And since the record was actually set on June 28, 2016, it's possible that Jianxia's eyelashes have grown even longer in the past 14 months. Do they grow that fast, though? Does she trim them? Does she shampoo them? Do they get split ends? Do they tickle her face? Has she ever tried Latisse? I NEED answers.

All the Guinness World Records publishers shared about Jianxia in a press release promoting the 2018 edition, which includes Jianxia's record, is that she discovered the scarily long lash "during an eighteen-month nature retreat she embarked on in 2013." According to the publishers, "She puts the growth down to the life she leads at one with nature." BRB, scheduling a camping trip to grow out my lashes.

Jianxia will be in good company in the Guinness World Records 2018 book, which hit shelves last week, according to the release. New additions to the book include the world's oldest bodybuilder, 85-year-old Californian Jim Arrington; the world's longest cat tail, which measures 17.58 inches and belongs to Cygnus, a Silver Maine Coon in Michigan; and the world's largest collection of teddy bears — 8,026 stuffed animals — owned by 68-year-old South Dakota resident Jackie Miley.

Of course, it wouldn't be a Guinness World Records book without a new set of shockingly long fingernails. The latest record was set by Houston-based nail artist Ayanna Williams, 60, who grew out her nails for 23 years until they reached their current length of almost 19 feet. In case you were wondering, they can take almost an entire week to paint and make putting on pants extra difficult. And if you're interested in giving Ayanna a run for her money, her strategy for growing out her nails includes cleaning them daily with antibacterial soap and avoiding washing the dishes (I'm sold!).
