Marks, there are certain mental states that are unique to growing adolescents that make asking the age of a 'child' very important in answering the questions posted by one. There is nothing illegal, immoral or wrong and no reason one should not ask the age of a poster especially when they themselves mention they're too young to understand what's going on. Teaching methods gradually change through early grade school and into high school for a reason, the mind's being taught grow in various stages which 'tint' comprehension and viewpoints dramatically. No one should be biased about a user here based on their age, but only the truly 'young' think age is unimportant. Again, I would like to stress to you the importance I perceive in your personal growth of learning a little bit more about basic psychology and mental development.. Learning electronics and the first epiphany of how a circuit is built and functions and being able to say "I understand that" is nothing compared to the same epiphany of understanding one's own conscious mind can bring. Turning the critical eye on oneself rather than others is a very hard thing to do, and one of the most important.
