Where did you listen to scientists exactly? WHERE?! You either did NOT watch the video or just decide to PICK what to hear. Either way, you are NOT listening to scientists. If you were, we wont be having this conversation now.
(This is not directed at you @AngelSeo , just a general observation)
We have to be careful when listening to scientists/doctors .
A lot of them are not studying these matters in detail , to really know what's going on . They're simply repeating what they heard , they don't have a deep , first hand knowledge of these subjects .
It's not their fault , medicine is a huge field , too big for anyone to know everything . But , because of ego , some of them pretend to know a lot more than they really know and this is very dangerous .
There's a famous quote : "Repeat a lie often enough and it becomes the truth"
Remember when doctors believed that smoking is healthy?
Or when they believed that asbestos doesn't cause cancer?
We shouldn't transform science into dogma .
