I was slow...and I didn't have a computer to program on until 8.
On the other hand, I've been teaching for ~20 years, and I've been teaching programming for half that. Learning to iterate through a collection of data structures is the killer feature in programming. Some folks get it....and immediately. Most folks who are not naturals take a lot longer to understand the concept...and most classes jump over it like it's easy. Usually 3-10 different explanations, and 5-20 examples will get folks over the hump.
