Could someone help me by correcting this paragraph? Some people think that the existence of comedy channels on YouTube is not necessary/ significant. Even these channels are considered as a main or additional source of income to their owners, but that's not the biggest benefit these channels maintain/offer. Everyone needs to do recreational activities whether psychological or physical ones. When you watch the funny content on those channels, your mood gets better. Because, everyone needs to have time for entertainment where he could laugh to reveal life tensions. Even if the content of those channels are considered to be silly by some people, but it plays an important role in changing people's mood.
