All excellent suggestions, Susie. I wonder if electronics, especially social media, television, and (strangely) e-mail are most responsible for falling intelligence levels. Television and videos are now used as babysitters, leaving small children constantly entertained so they don't learn how to process their own thoughts. Also, when people had to write letters, there was a thought process involved. Now, we all just send texts or e-mails or just tell our phones to call whomever we wish to contact.
