True, you are right and I've never thought of it that way. We all have our strengths and weaknesses and surely without everyone being "classified" as something we are all incapable or terrible at doing certain things while we are tremendous at others. It's like the fish climbing a tree versus certain types of animals swimming. I love that saying. If you test them at what they were meant to do they'll pass with flying colors. Problem is it's impossible to classify humans in such a visual / species type of way. We are too indistinguishable.
