Yes, Emily is a fine example of smart young members here. I had the opportunity to meet her last weekend and she is definitely doing things right with her pets. It shows just by her posts and questions.
Another great example is garterguy, who just found a shelter to donate his time to and help animals that really need it. Now that is a great way to learn hands on about different species and their care.
I'm sure I'm missing a ton of other great young smart members here, sorry! I don't check the age of all who post
So it really doesn't have anything to do with your age, only with your MATURITY and COMMON SENSE which you are definitely LACKING
