In his seminal work on cognitive development, Piaget (1951) discusses children’s pre-operational stage and the notion of egocentrism. During this stage which begins at around the age of 3 till around 7 years’ old, children do not, consciously distinguish the self and others.
Hummingbirds are nature’s more agile flyers among birds. They are capable of not only sustained hovering flight, but also fast forward flight and various rapid manoeuvres. Like a hummingbird, a coach hovers over and uses the same multi-motion flight technique to gain better view and visibility to facilitate the journey.
