Shadix,

I think we are getting tired of these questions, so why don't we turn the tables and have you answer the following question:

I used to teach my students in math classes the following:

- if you are 2 years old, and your neighbor is 5 years old, there is a huge divide between you.
- if you are 92 years old, and your neighbor is 95 years old, you are basically age peers.

The question: What concept did I teach this way?
