Is there a normal body temperature? Most people think of 'normal' body temperature as 37C (98.6F), measured using a thermometer in the mouth. However, the concept of there being a normal body temperature is somewhat misleading. In fact normal body temperature can vary according to a wide range of factors including a person's age, the time of day and whether someone is active or not. The 'normal' benchmark for body temperature was established by a 19th century German physician called Dr Carl Wunderlich. He is credited with taking temperature readings from thousands of patients, which led him to propose that 37C was normal body temperature.

YouTube channels are FREE. It will cost you nothing to create a channel, and it won't cost you anything to upload your videos there. You only need a Google account (also free), and you can even create multiple YouTube channels. All zero cost. Actually, you might even turn a YouTube channel into a revenue source. And that leads to a different set of questions: How much does it cost to produce videos for YouTube? or How much would it cost me to produce videos and grow a channel up to the point I can make a living out of YouTube? Such questions are much broader as well as the possible answers! There are YouTubers that invest basically only their time - recording, editing and uploading daily vlogs all from their smartphones.
