Much of what you say about hormones has been considered scientific fact for a long time -- but I wouldn't be surprised to learn that the facts have been banished by political correctness.

Plus, Facebook is indeed a harmful product for society at large (like cigarettes), and often has bigger negative impacts on younger users (again like cigarettes).

The combination of these is obviously bad...but Facebook knowing it and hiding the fact is very much (again) like what tobacco companies did.
