Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Ageing, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. ----Rdp060707|Let's discuss about the plans 05:59, 19 March 2021 (UTC)

Please do not add or change content, as you did at Cognitive development, without citing a reliable source. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. Megaman en m (talk) 11:55, 20 March 2021 (UTC)
