I feel that there are many problems in society today.
However, there is one critical one that needs to be addressed. People who look at their phones are vulnerable to someone mussing them, or accidental injury. It seems that today, the main cause of death is texting while driving. Texting while driving leaves them oblivious to anything else.
Multi-tasking with something like that is very hard to do, which they do not seem to realize. While they are texting, they wouldn't notice either stop lights or a turn which can result in fatal injuries.
