In today’s modern world there are so many things competing for our attention. It’s hard to focus. I feel sorry for future generations. Most of their minds are probably turned to mush by age 7. How can they retain information when they are daydreaming about mind craft, Rihanna, twerking, and the latest funny YouTube video they saw.? As A 37 year old woman I feel overwhelmed. I can’t imagine the angst young people feel. The Cherry on top of this mind mess is puberty. I now have a greater appreciation of the challenges young people face. Good luck keeping your mind on calculus and off of pornhub.
