Our amazing nature

Since I was a child, I had always wondered (if you use Past Perfect here then it means you no longer wonder.  It might make more sense to use Present Perfect - as this means you started wondering in the past and still wonder now) about why do the people do what they do.
I remember myself looking attentively to  at each movement of persons  people and other beings around like little insects and people's pets (not really sure want you to say with this sentence). Later on, when it was time for me to choose a university degree, I thought about being a psychologist, at  in the end I didn't choose for that university degree because I think we can experience and learn from behavior in the daily life, and we can explore the amazing human, animal and insect minds in many ways.
Finally, In the end, I became a biotech engineer, and... You wondered what happened? I got amazed now for  really interested in another behavior world: the microscopic world, including bacteria, fungi, algae, and protozoans.
