I can't tell if it's because I'm just getting older or because I'm surrounded by distractions (both electronic and caused by this open office nightmare trend), but my ability to _concentrate_ seems to go down every year. When I was in my 20's, I could focus on a math problem for hours at a time. Now, I need to take a break and look at something else every 10 minutes. Is the world changing to make it harder to accumulate knowledge and improve intelligence?
