Hello, I'm Johand199. An edit you recently made to Lactose intolerance seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Johand 199 (Talk • Contribs)  18:12, 3 March 2020 (UTC)
