It would catastrophic to stop ageing. We already have a massive overpopulation problem. Within our lifetime, we will likely see wars waged over food and resources. That is unless something is done or a good percentage of the population dies off.
I like your thumbnails. I think maybe your videos might be a little long. Not many people will watch a 1hr video. I read somewhere that big youtubers try to make their videos 10 - 15 mins long. After that people start to get bored.
