I found this video interesting because it doesn't just touch on what is happening in our brains that is changing due to phone use, but it also talks about the change in our physical appearance due to phone use.
I found the very first fact very interesting that out of the 7 billion people on earth 6 billion have a phone and only 4.5 billion have access to a toilet. This also made me wonder if these were mobile phones or if this was also regular phones as I felt this number was rather high.
I am also a huge fan of our sleep cycles, I enjoyed how they talked about the change in sleep habits due to phone use as not many people think about proper sleep hygiene.
