It's pathetic how some end up taking all these decisions based on research and statistics... If you don't want a dog just don't take one instead of trying to find scientific reasons on why not to own one and then writing an article about it.
The 2nd best thing after uninstalling the fb app from the phone was to log out from it in my laptop's browser, make sure my password is a generated one (so I can't enter it manually) and also make sure it won't autocomplete when I go to facebook.com.
Now if I want to access it I have to open the Password Manager, copy the password and then paste it ... which are too many steps for me to take in order to check it out :)
So, in the past 1-2 months I think I spent in total 1-2 hours on facebook.
