This latest Dr. Bunsen post by Seth Brown is a good introduction to his site as it links to some of his best posts. But it also stands on its own as a thoughtful discussion of managing information input and processing. It also has one of the best opening lines I've read in a long time.
The human brain has a capacity to store an estimated 2.5 petabytes of data and execute 6.418 nerve impulses per second.
It's a good read and should not be judged by the beard alone.
