C-sections were still seen as the last option before 1965.This outdated procedure involved removing a part of the pelvic bone to allow the delivery. It was performed without anesthesia using a small knife and a saw.According to Pharmacy Times, two Scottish doctors, John Aitken and James Jeffrey, developed a hand-cranked tool for this procedure in 1780. It was a small instrument, no bigger than a kitchen knife. The intention for this serrated metal "teeth" on a chain tool was to cut through the bone with ease and more quickly.In the late 19th Century, this tool became an early prototype for what are now mechanized chainsaws. By the 1920s, this mechanized variant was adopted by the timbre industry and has since been used as a wood-cutting tool.TikTok is a short-video hosting platform owned by a Chinese company, ByteDance. It hosts a variety of videos, from pranks to stunts, jokes, dances, and more. A variety of "trends" have risen within the platform, including challenges, memes, dances, and lip-sync videos.The "Before and After" trend, as the name suggests, records the reactions in users after googling a question like "where does vanilla flavoring come from?" or "How did Barney the dinosaur die?" Another version of this trend involves users reacting to a fact or information.
