Two games and a bad back

• My mom got curious about the Bejeweled game so I installed Bejeweled Blitz (it was the one I could download for free) and immediately got addicted. I tried to get both my parents to play it. My mother found it entertaining tho she was rather slow in spotting potential three-matches. My father on the other hand had difficulty picking up on the idea especially when he is a partially red-green color blind.
• I thought I'd mention that I also installed the Minion Rush game which was found to be a lot of fun. With both Bejeweled Blitz and that in our iPad, I suddenly find the likes of Angry Birds and Candy Crush boring and slow.
• Despite more or less exercising regularly (walking + strength training), my lower back has curiously began aching.  It might be due to my sitting for long periods of time while studying and programming for my automata theory course.
