Are older people better programmers? | Javalobby: "Fast programmers who produce disorganized code rely on their superior short term memory to get things done. These programmers get worse with age as their short-term memory weakens. They tend to drop out of the field.
Slow programmers who produce well-organized and readable code avoid relying on short-term memory. They tend to get faster and better with age as they accumulate in their long-term memory an ever increasing portfolio of strategies, patterns and techniques."
